Kissinger’s discussion of détente centers on Nixon’s attempt to manage Cold War rivalry through linked negotiations.
In 1994, Henry Kissinger published the book Diplomacy. He was a renowned scholar and diplomat who served as the United States National Security Advisor and Secretary of State. His book provides an extensive sweep of the history of foreign affairs and the art of diplomacy, with a particular focus on the 20th century and the Western World. Kissinger, known for his alignment with the realist school of international relations, inquires into the concepts of the balance of power, raison d'État, and Realpolitik across different eras.
His work has been widely praised for its scope and intricate detail. Yet, it has also faced criticism for its focus on individuals over structural forces, and for presenting a reductive view of history. Also, critics have also pointed out that the book focuses excessively on Kissinger's individual role in events, potentially overstating his impact. In any case, his ideas are worthy of consideration.
This article presents a summary of Kissinger's ideas in the twenty-ninth chapter of his book, called "Detente and Its Discontents".

Linkage and the Reopening of European Diplomacy
Kissinger begins from the claim that the Nixon Administration sought to recover strategic freedom after Vietnam by refocusing foreign policy on a wider international design. The opening to China, Soviet negotiations, and the effort to end the Vietnam War formed one part of that system. The Berlin settlement, the reorientation of Middle Eastern diplomacy, and the European Security Conference formed another. This was the practical meaning of linkage: Soviet recklessness in one field would carry a diplomatic price in another.
Europe was the first major testing ground: the continent had been politically frozen since the Berlin Wall and the consolidation of the two German states. Until Willy Brandt became West German chancellor in 1969, the Federal Republic had insisted that Bonn alone represented Germany. Under the Hallstein Doctrine, West Germany refused to recognize East Germany and broke relations with most governments that did. The doctrine had once served the purpose of keeping the German question open, but by the late 1960s it had become difficult to sustain. German unity had disappeared from serious East-West negotiations, while the allies continued to affirm reunification in principle despite their unwillingness to risk war for it.
Charles de Gaulle had already sensed that the Cold War system might be loosened by a European approach to Moscow. His formula of “detente, entente, and cooperation” sought to persuade the Soviet Union that Western Europe was more than an American dependency and that Moscow’s conflict with China might make Eastern Europe more negotiable. Kissinger credits de Gaulle with perceiving the new fluidity but judges that France lacked the power to exploit it. West Germany would not separate from the United States under French leadership, and de Gaulle refused any German role in a European nuclear deterrent. Still, his initiative prepared the ground for Brandt’s Ostpolitik, even though the Soviet invasion of Czechoslovakia in 1968 ended de Gaulle’s effort.
Brandt’s policy was startling in its reversal of the older West German assumption that unity depended on firmness within the Western alliance alone. He argued that the stalemate created by strict nonrecognition could be eased by rapprochement with the communist world. Accordingly, West Germany would recognize the reality of East Germany and accept the Oder-Neisse border with Poland. In Brandt’s logic, that external recognition would open the way to better relations with the Soviet Union, with reduced tension making reunification less impossible over time. Even if unity remained distant, Brandt expected better conditions for East Germans and a less brittle European order.
Ostpolitik, Berlin, and the Management of German Power
The Nixon Administration initially regarded Ostpolitik with suspicion. A West German effort to court the East raised the possibility that the two German states might eventually converge around a nationalist or neutralist program, the very outcome that Konrad Adenauer and de Gaulle had feared for different reasons. Washington also worried that Brandt lacked Adenauer’s commitment to the Atlantic alliance. France had already weakened the Western front by leaving NATO’s integrated military structure and seeking its own relationship with Moscow. A West German breakaway carried far greater danger: Germany was Western Europe’s strongest economy and the country with the most powerful territorial grievance.
Yet Kissinger explains that the alternative to supporting Brandt was more dangerous than Ostpolitik itself. The Hallstein Doctrine was collapsing, and no Western ally was ready to back a German challenge to the postwar division of Europe. If Bonn pressed reunification too directly, Moscow would resist, and memories of German aggression could split allied attitudes in the Atlantic alliance. Given Germany’s capacity to disrupt the European settlement, American policy had to keep West Germany anchored in NATO and the European Community. Supporting Ostpolitik therefore became a way to guide German diplomacy rather than lose control of it.
Washington’s support came with strict linkage. The Nixon Administration insisted that German concessions to the East had to be connected to concrete guarantees for West Berlin. That link mattered: Brandt was offering tangible recognition of existing borders and of East Germany in return for less tangible improvements in relations. Without a four-power agreement protecting access to Berlin, the city could become more vulnerable after East Germany gained greater international legitimacy. With Berlin’s legal status resting on the wartime rights of the United States, Britain, France, and the Soviet Union, only the four powers could provide the necessary guarantees.
The result was the 1971 Four Power Agreement on Berlin, which secured Western access and the freedom of West Berlin. Kissinger treats this as one of detente’s major achievements; Berlin had been a recurring crisis point for more than two decades. After the agreement, it disappeared from immediate flashpoints until the fall of the Berlin Wall. Ostpolitik also produced treaties between West Germany and the Soviet Union, Poland, and East Germany. The Soviet insistence on recognition revealed, in Kissinger’s view, insecurity rather than strength: a nuclear superpower still wanted West Germany to confirm the borders created by Stalin.
These negotiations also gave Moscow a reason to behave carefully. While the treaties awaited ratification in Bonn, Soviet leaders avoided actions that might endanger approval. Afterward, they remained reluctant to drive West Germany back toward Adenauer’s rigidity. Kissinger connects this restraint to broader Soviet behavior, including Moscow’s muted response when Nixon mined North Vietnamese harbors and resumed bombing Hanoi. As long as Nixon retained domestic strength, detente allowed the United States to connect European incentives, German diplomacy, and Soviet restraint across multiple theaters.
The Middle East and the Reduction of Soviet Influence
In the Middle East, the Nixon Administration used detente differently. In Europe, it linked several negotiations to stabilize a dangerous status quo. In the Middle East, Kissinger argues, Washington used detente as a safety net while it reduced Soviet influence. During the 1960s, the Soviet Union had become the main arms supplier to Egypt and Syria and a diplomatic advocate of radical Arab positions. As long as Moscow seemed to profit from crisis and stalemate, Arab leaders had little reason to move toward compromise under American auspices.
The Nixon strategy rested on what Kissinger presents as the basic geopolitical reality of the region: Israel was too strong, or could be made too strong, to be defeated by its neighbors, and the United States would oppose Soviet intervention. The Soviet Union could raise tensions, supply weapons, and threaten involvement. It lacked the ability to deliver a settlement. The key to peace lay in Washington. If the United States held firm, either Moscow would have to contribute to a real settlement or an Arab client would turn toward American diplomacy.
The path to that result was difficult. In 1969, Secretary of State William Rogers proposed a plan based on Israel’s 1967 borders with minor adjustments in exchange for peace. It failed because the underlying political conditions remained unchanged: Israel rejected a predetermined border formula, while Arab governments remained unprepared for a serious peace commitment. In 1970, Egypt launched the war of attrition along the Suez Canal, Israel responded with deep air strikes, and the Soviet Union installed a major air-defense system in Egypt. The same year, the PLO’s power inside Jordan provoked King Hussein’s crackdown and Syrian intervention. Israeli mobilization and a major American naval reinforcement in the Mediterranean followed. The crisis ended when Syria withdrew and Moscow avoided confrontation with Washington, demonstrating to Arab governments which superpower mattered most in an emergency.
The first clear consequence came in 1972, when Egyptian President Anwar Sadat expelled Soviet military advisers and began secret contacts with the White House. The 1973 Arab-Israeli War then transformed the diplomatic field. Egypt and Syria surprised both Israel and the United States, partly because American intelligence had assumed Israeli superiority made an Arab attack unlikely. The war restored Arab military confidence but still ended with Israel across the Suez Canal and near Damascus. Arab leaders therefore needed American influence to restore territory and open a path toward peace.
Sadat recognized this first. He abandoned an all-or-nothing approach and turned to Washington for a step-by-step process. Even Syria’s Hafez Asad appealed to American diplomacy over the Golan Heights. In 1974, disengagement agreements with Egypt and Syria began Israeli withdrawals in exchange for Arab security assurances. A second Israeli-Egyptian agreement followed in 1975, and the process culminated in the 1979 Egyptian-Israeli peace treaty under President Carter. Kissinger notes that later administrations continued this American-centered peace process, while the Kremlin played no significant role. For him, this proved that detente was a method of geopolitical competition, not a sentimental search for cooperation: by giving Moscow a stake in restraint while exposing its inability to deliver Arab objectives, Washington moved the Soviet Union to the margins of Middle Eastern diplomacy.
Detente Against American Political Traditions
The foreign policy successes of Nixon’s first term did not produce domestic consensus. Kissinger argues that every major shift in American foreign policy has faced resistance, but the detente debate unfolded under unusually destructive conditions. Vietnam had shaken public trust, and Watergate deprived Nixon of the moral authority needed to defend a difficult strategy. Foreign policy in the American system requires presidential leadership: Congress divides issues into separate legislative decisions, and the media can advise without executing. Only the president can integrate choices into long-range policy.
For Kissinger, Watergate was disastrous; Nixon’s approach needed public education. The policy challenged American exceptionalism, especially the belief that foreign policy should express transcendent values and move toward final solutions. Nixon and his advisers saw a world of ambiguous challenges, competing national interests, incremental gains, and problems that could be managed rather than solved permanently. This did not mean abandoning American values. It meant that those values could no longer be translated into immediate final outcomes, as Wilsonian language often implied.
Detente also offended the American tendency to divide countries into friends and enemies. Nixon treated the Soviet Union as both adversary and collaborator: adversary in ideology and geopolitical competition, collaborator in preventing the conflict from turning into nuclear war. Many Americans, exhausted by Vietnam, sought moral reassurance rather than calculations of interest. In the absence of a morally persuasive presidency, liberals and conservatives attacked Nixon from different directions. Liberals distrusted the emphasis on national interest and balance of power even when they approved of specific results such as the opening to China or reduced tension with Moscow. Conservatives viewed the struggle with communism primarily as an ideological conflict and treated compromise with the Soviet Union as a form of retreat.
Neoconservatives added a further source of opposition. Many were anticommunist Democrats alienated by the radical wing of their party, especially after George McGovern’s 1972 campaign. They might have been expected to support Nixon’s persistence in Vietnam, but they distrusted him and feared he might sacrifice vital interests to save his presidency. Thus critics who differed on defense, arms control, and moral purpose converged in hostility to detente.
The Nixon White House also worsened its political position by shifting diplomacy into direct presidential channels and bypassing much of the bureaucracy. Ambassador Anatoly Dobrynin became part of a back channel between the Kremlin and the White House once Soviet leaders understood that Nixon made the key decisions. This made diplomacy more direct but angered excluded officials, who could imagine that concessions would have been avoidable had their advice been followed. The administration therefore found itself defending a successful foreign policy against uneasy conservatives, frustrated liberals, neoconservatives, and a resentful bureaucracy.
SALT, Strategic Equality, and the Jackson Challenge
The controversy over detente became especially intense in the debate over arms control. Senator Henry Jackson, a Democrat from Washington, emerged as the most formidable critic. He had supported Nixon on Vietnam and helped guide the Anti-Ballistic Missile program through the Senate, but he opposed the ABM Treaty and then broadened his criticism to the whole framework of Soviet-American relations.
The strategic background was complicated by congressional pressure against defense spending. Nixon’s original ABM program envisioned a dozen sites, but Congress reduced the number until only two remained in the budget. The Defense Department, fearing unilateral reductions, came to favor arms control as a way to preserve leverage. Nixon’s correspondence with Kosygin produced the basis for the 1972 Strategic Arms Limitation Talks agreements. The Soviets wanted to limit defensive systems while postponing limits on their rapidly expanding offensive missiles. Nixon refused that imbalance, and the final framework linked offensive and defensive limitations.
The ABM Treaty confined each side to two defensive sites and 200 launchers. Nixon accepted this to preserve a nucleus of missile defense that Congress might otherwise eliminate. The more controversial measure was the five-year Interim Agreement freezing strategic offensive missile launchers. The United States had already set its own levels years earlier and had no program to increase them. The Soviet Union had to dismantle older missiles to meet the ceiling, though it retained more launchers. Critics seized on this numerical inequality even though American forces had advantages in accuracy, multiple warheads, and bombers outside the ceilings.
Kissinger argues that the debate transformed a voluntary American force posture into the appearance of a negotiated concession. A level that had seemed sufficient before SALT became alarming once it appeared in an agreement with the Soviet Union. The word “inequality” acquired political power that technical explanations could not overcome. By the time the administration discussed launchers, warheads, and bombers, the public impression of a missile gap had already formed. Modernization plans and negotiated ceilings only deepened the dispute.
Yet Kissinger grants that the criticism reflected a real concern. Jackson and his allies feared that arms control had become a substitute for strategy and that military programs were increasingly justified as bargaining chips rather than as instruments of defense. Behind the technical dispute lay the larger problem of strategic equality. The doctrine of Mutual Assured Destruction rested on each side’s capacity to devastate the other. For Kissinger, this doctrine could not sustain alliances or morale indefinitely; it made nuclear forces useful mainly to deter nuclear use, not to respond to ordinary political crises. SALT made visible a nuclear stalemate that had already existed.
Jackson’s nightmare was strategic vulnerability, especially the possibility that the Soviet Union might gain decisive superiority. Nixon’s nightmare was geopolitical vulnerability: the accumulation of marginal Soviet gains in a world where American nuclear power was too apocalyptic for limited crises. Jackson focused on weapons balances and sought to force Soviet strategic forces into patterns preferred by the United States. Nixon focused on the global distribution of political power and doubted that Washington could redesign Soviet forces while Congress cut defense budgets. In Kissinger’s final assessment, the two positions were more complementary than either side admitted. One emphasized the technological and military dimension of the Cold War, the other its geopolitical management.
Human Rights, Jewish Emigration, and the Limits of Linkage
As arms control proved too technical to carry the whole philosophical dispute, the debate shifted toward human rights. Kissinger accepts the moral importance of the objective while disputing the attempt to make ideological confrontation the overriding purpose of foreign policy. The first major case was Jewish emigration from the Soviet Union. Before 1969, no administration had made it a significant item in Soviet-American diplomacy. The Nixon Administration began raising it quietly through the presidential back channel, signaling that Soviet behavior would be noticed at the highest level.
This tacit bargaining produced results. In 1968, only a few hundred Soviet Jews had been allowed to emigrate. By 1973, the number had risen to tens of thousands. The White House also submitted lists of hardship cases, many of whom were eventually allowed to leave. The administration did not publicize these efforts or claim credit; the method depended on avoiding a formal confrontation that might force Moscow to refuse publicly.
The issue changed in 1972 when the Soviet Union imposed an exit tax on emigrants, supposedly to recover the cost of their education. Jewish organizations appealed both to the administration and to Senator Jackson. Jackson responded by linking human rights to trade. The United States had agreed at the 1972 summit to grant the Soviet Union Most Favored Nation status in connection with a Lend-Lease settlement. Since Most Favored Nation status meant nondiscriminatory normal trade rather than a special privilege, its practical economic significance was limited. Its political significance was enormous: Jackson’s amendment turned Soviet emigration into a matter of congressional legislation.
At first, congressional pressure reinforced the administration’s private diplomacy. Soon, however, method became substance. Nixon regarded Jewish emigration as a humanitarian cause worth pursuing. He rejected the subordination of all Soviet-American relations to that issue. Jackson and his supporters treated emigration as a surrogate for the wider ideological struggle against communism. After the Soviets revoked the exit tax, critics demanded higher emigration figures and broader removal of restrictions, while the Stevenson Amendment limited Export-Import Bank loans to the Soviet Union. As a result, Moscow ended up worse off commercially after detente than before it.
Kissinger’s complaint is that critics moved linkage from restraint in Soviet foreign policy to direct pressure for domestic upheaval inside the Soviet system. Nixon had tried to make improved trade dependent on moderation abroad. His opponents sought to use trade, arms control, and public human rights demands to force internal change in a still powerful nuclear rival. The moral question was not whether human rights mattered, but whether the United States, emerging from Vietnam and Watergate, could sustain an unlimited agenda of confrontation. Kissinger accepts that bolder pressure later had advantages, especially in the Reagan years, but argues that the early 1970s made such a course unrealistic.
Helsinki and the Paradox of Soviet Legitimacy
The Conference on Security and Cooperation in Europe, which produced the Helsinki Accords, receives one of the chapter’s strongest retrospective defenses. Kissinger presents the conference as a product of Soviet insecurity. Even with a vast military establishment and control over Eastern Europe, the Kremlin wanted Western recognition of the postwar status quo. In this sense, the conference became Brezhnev’s substitute for the German peace treaty that Khrushchev had failed to force through the Berlin crises.
Moscow may have hoped that a European security process would create institutions that diluted NATO or reduced the importance of the American military presence in Europe. Kissinger argues that this was a miscalculation. No NATO country was ready to substitute conference declarations for the alliance’s military reality. Moreover, the process eventually gave Western governments, including the United States, a recognized voice in the political arrangements of Eastern Europe.
The Nixon Administration initially hesitated but then accepted the conference as another item in its broader linkage strategy. The borders of Eastern Europe had already been recognized in postwar treaties, in Brandt’s Ostpolitik agreements, and by other Western governments. Since the allies were pressing for the conference, Washington decided to shape the outcome rather than stand aside. The United States made its participation depend on progress elsewhere, including the Berlin agreement and the opening of Mutual Balanced Force Reduction talks.
The final Helsinki documents did not grant Moscow the sweeping legitimation critics feared. The recognition of borders was limited to a pledge not to alter them by force, which repeated the United Nations Charter. The text also affirmed that frontiers could be changed peacefully and by agreement. This preserved the principle that the European settlement was not morally or legally frozen forever.
The decisive provision turned out to be Basket III, which concerned human rights. Its Western drafters hoped to create an international standard that would limit Soviet repression. Dissidents and reformers in Eastern Europe used the provisions as a rallying point against Soviet domination and communist rule. Kissinger singles out Václav Havel in Czechoslovakia and Lech Wałęsa in Poland as activists who transformed Helsinki’s language into political leverage. Thus the same conference that Moscow had sought as confirmation of its conquests helped undermine the legitimacy of its empire.
Contemporary reactions missed this long-term effect. Ford was accused of accepting a historic sellout by attending the 1975 summit and signing the Final Act. Kissinger insists that the United States was not on the defensive at Helsinki. The communist governments, rather than the democracies, were being asked to live up to principles they had signed. In his interpretation, the conference both moderated Soviet conduct during its preparation and later accelerated the unraveling of Soviet control in Eastern Europe.
The Unfinished Synthesis of Realism and Idealism
The chapter closes by returning to the deeper American argument over peace, power, and moral purpose. Nixon’s “structure of peace” responded to a country exhausted by distant war, but peace as the absence of conflict was too passive to sustain American policy. The Nixon Administration offered a more realistic view of international relations: a world of competing interests, strategic equality, regional crises, and incremental change. Nevertheless, Kissinger concedes that this view was not grounded in principles familiar enough to the American public.
The critics had the opposite weakness. They invoked American ideals with force while often acting as if the international environment imposed no limits. They demanded immediate transformation of Soviet conduct and domestic practice at a moment when the United States was politically weakened, the presidency was collapsing, Congress was reducing the president’s ability to use force, and defense and intelligence capabilities were under attack. The result was a stalemate in policy. The incentives of trade were withdrawn, and stronger means of confrontation failed to appear. SALT stalled, Jewish emigration slowed, and Soviet or Soviet-aligned advances resumed in places such as Angola.
Kissinger’s final judgment is not a simple defense of every Nixon position or a dismissal of every critic. He argues that the United States needed both geopolitical realism and moral confidence. Detente was necessary in a world where nuclear parity and new diplomatic fluidity made old formulas inadequate. Realism alone still failed to satisfy a country whose great foreign policy initiatives had always drawn energy from moral purpose. Conversely, idealism detached from strategy could produce demands the United States was not prepared to enforce.
The tragedy of the 1970s, in Kissinger’s account, was that Vietnam and Watergate prevented a serious synthesis. A strong presidency might have integrated restraint, defense, and negotiation into a coherent policy. It might also have joined human rights and resistance to Soviet expansion to that same design. Instead, each camp pushed one part of the problem to an extreme. Liberals feared militarization and overextension, conservatives feared moral and strategic retreat, neoconservatives demanded ideological confrontation, and Nixon emphasized geopolitical management. Because the presidency had lost authority, these views collided without producing a durable settlement.
The later collapse of communism allowed Kissinger to see the opposing American camps as more complementary than they appeared at the time. Communist weakness and Western pressure both contributed. So did human rights activism, strategic modernization, and geopolitical containment. The Nixon Administration helped hold the international system together during a dangerous transition. Later administrations supplied elements that Nixon’s policy lacked or was politically unable to sustain. Once the Soviet challenge disappeared, the United States faced a new problem in the 1990s: defining national interest without the opponent that had structured American diplomacy for nearly half a century.
