Detente began to unravel in the Third World. Khrushchev had reached out to national liberation movements in an ostentatious but tentative fashion. In the early 1960s, the Soviet Union had almost no specialists on Africa: a subsection on Africa was just being created in the International Department of the Central Committee in 1961. Under Brezhnev, Soviet support for real or potential Third World allies shifted in emphasis from economic to military aid. The Kremlin sold arms, sent military advisers, and sought bases in some Third World Countries. Moscow’s most important Third World allies were Cuba, India (after the signing of the Soviet-Indian Treaty of Friendship and Cooperation in August 1971), and Vietnam. In the Middle East, Syria, Iraq, Libya, and Egypt were particularly significant. While there was no Soviet master plan for the Third World, the Soviet Union, trying to emulate the United States, was becoming a global power, with a growing naval presence in all parts of the world. However, there was a strong perception of a Soviet master plan within the Carter administration, championed by national security adviser Zbigniew Brzezinski, who had significant influence on the new president’s thinking, especially through his weekly national security reports.236
Even as Soviet aid to Third World countries grew, some in the Soviet leadership, especially Kosygin, tried to limit it. He hoped to make relations with Third World countries more “mutually beneficial," by basing them on the "distribution of labor." Kosygin was especially interested in expanding Soviet influence in South Asia. During the September 1965 hostilities between India and Pakistan, Kosygin successfully mediated the conflict and persuaded the two countries to sign the Tashkent Declaration in January 1966. In the late 1960s, especially after the Soviet-Indian Treaty was signed, Moscow’s Indian connection helped to balance the US-Chinese rapprochement. The alliance between the USSR and India was cemented during the Indo-Pakistani war of December 1971, which India fought successfully with Soviet armaments. The Chinese were deterred from intervening on Pakistan’s side by the Soviet-Indian alliance.
Meanwhile, in the Middle East, the post-Khrushchev leadership initially tried to deemphasize the former leader’s support for Arab states as the main source of Soviet influence in the region. Kosygin’s successful mediation of the conflict between India and Pakistan kindled Soviet aspirations to replace the United States as the main Middle East peace mediator. However, Egypt, the most important Soviet ally in the area, resisted this idea.
In the spring of 1967, the Soviets found themselves being manipulated by Syria and Egypt. Soviet arms sales to these two countries encouraged their belligerence toward Israel, while Soviet pressure on them to be more conciliatory had no effect. Shortly before the outbreak of the June 1967 war, the Soviets allowed Egypt to mobilize troops to deter a possible Israeli attack against Syria, about which Podgornyi informed the Egyptian government in May 1967. Strong rhetorical support for the Arabs then undermined Soviet ability to serve as a mediator.
Once hostilities broke out, and the devastating defeat of Egypt, Syria, and Jordan became apparent, Moscow felt it had no choice but to threaten intervention if Israel did not stop its advance. At the same time, however, the Kremlin turned to the United States for joint mediation. The shift from seeking to be the sole peacemaker in the Middle East to understanding the need for US-Soviet cooperation was a turning point in Soviet Middle East policy. In July 1967, the Soviet Union and the United States successfully collaborated on UN resolution 242, which envisioned an Israeli withdrawal from the occupied lands in exchange for Arab recognition of Israel’s right to exist. In 1970, Brezhnev even proposed a gradual restoration of relations with Israel, but Suslov and Gromyko opposed it. They insisted that Soviet policy toward the Middle East stay the same until a full peace settlement in the region was reached. According to Dobrynin, Brezhnev gave in and continued the pro-Arab policy.237
Notwithstanding the lessons learned during the 1967 war, and the newly found joint mission with the United States in the region, the Soviet Politburo, acting in response to the urgent requests of its Arab allies, decided to resupply their armies. Thousands of Soviet military personnel were sent to Syria and Egypt, and the Soviet Union acquired naval rights in Arab countries. Although Egypt and Syria were resupplied with up to $5 billion worth of military equipment, Egypt wanted even more, and so during the war of attrition in 1969-70, Soviet fighter pilots were dispatched there. A treaty with Egypt was signed in May 1971, and a similar treaty with Iraq in April 1972. Driven by fear that the United States would marginalize Soviet efforts to be a leading mediator in the region, Moscow was seeking to consolidate its own sphere of influence in the Middle East,
Soviet interests suffered a major setback when, just six weeks after the Moscow Brezhnev-Nixon summit, Egyptian president Anwar Sadat expelled over 20,000 Soviet military advisers, technicians, and military aircraft from Egypt. Sadat had pursued secret contacts with Kissinger for a long time before that decision was made, apparently exploring a more promising alliance. His turnaround made it even more important for the Soviet Union to reach an understanding with the United States on their joint role in the Middle East, an effort that jibed with Brezhnev’s personal dream of joining with Nixon to exert pressure on Soviet and American allies in a crisis situation. During his second American summit with Nixon in San Clemente, California, in June 1973, Brezhnev had a famous middle-of the-night three-hour session with the president. Among other things, Brezhnev proposed that it was time for the two leaders to reach an agreement on the Middle East among themselves and then to "bring to bear [their] influence" on their respective allies to reach the settlement that would bring a lasting peace to the region. Brezhnev was passionate and unrelenting, urging Nixon to step in personally before it became too late.238
Nonetheless, US-Soviet collaboration failed its first test in the region just a couple of months after the summit. After the Egyptian and Syrian attack against Israel on October 6,1973, Moscow and Washington accused each other of using delaying tactics in order to assist their allies in gaining more territory. When the ceasefire collapsed, and the Arabs seemed to have gained momentum, the United States put its forces on a very high level of alert, precipitating a crisis that threatened a direct US-Soviet clash. The ceasefire was eventually reestablished and hostilities ended, but this episode undermined Washington’s reliability as a partner in Moscow's eyes, thus compromising the overall health of US-Soviet detente.
