• 1972 – SALT I agreement signed, limiting strategic nuclear weapons with the United States.
• 1975 – Helsinki Accords recognise European borders and human rights principles.
• 1979 – Soviet invasion of Afghanistan begins; SALT II signed but not ratified.
• 1980 – International boycott of Moscow Olympics in response to Afghanistan invasion.
• 1979-1985 – Collapse of détente leads to the 'Second Cold War'.

The Brezhnev Doctrine and the invasion of Czechoslovakia

During Leonid Brezhnev's tenure as Soviet leader, maintaining communist control over Eastern Europe was a priority. The Brezhnev Doctrine and the subsequent invasion of Czechoslovakia in 1968 were defining moments that underscored the Soviet Union's determination to prevent any deviation from socialism in its sphere of influence.

The Brezhnev Doctrine

Announced in 1968 after the invasion of Czechoslovakia, the Brezhnev Doctrine declared that the Soviet Union had the right to intervene in any socialist country where communism was threatened. It aimed to justify military action to preserve the unity of the socialist bloc.

This policy effectively limited the sovereignty of Eastern European states, ensuring they remained aligned with Moscow's interests under the guise of protecting socialism.

The invasion of Czechoslovakia in 1968

• Context of the Prague Spring - In early 1968, Czechoslovak leader Alexander Dubček introduced reforms under the Prague Spring, promoting 'socialism with a human face'. These included greater political freedoms and economic liberalisation, which alarmed Soviet leaders fearing a loss of control.
• Reasons for intervention - Moscow viewed these reforms as a threat to the cohesion of the Warsaw Pact and communist ideology, worrying that similar movements could spread to other satellite states.
• Operation Danube - In August 1968, over 500,000 troops from the Soviet Union and other Warsaw Pact countries invaded Czechoslovakia in a coordinated military operation named Operation Danube, swiftly occupying key areas.
• Crushing of reforms and 'normalisation' - The invasion ended the Prague Spring, with Dubček removed from power. Gustáv Husák was installed as leader, enforcing 'normalisation' - a return to strict communist orthodoxy, censorship, and suppression of dissent.
• International reactions - Western countries condemned the invasion but took no direct action, constrained by Cold War tensions. Some communist parties in Europe, like those in Italy and France, distanced themselves from Soviet actions, revealing cracks in global communist solidarity.

Détente with the West and its key agreements

Amidst Cold War rivalries, Brezhnev pursued a policy of détente with the West, aiming to reduce tensions and secure economic and political benefits for the Soviet Union. This period saw significant agreements, though it was not without limitations.

Motives for pursuing détente

• Economic needs - The Soviet Union sought to reduce military spending, which was a heavy burden on its economy, and gain access to Western technology to modernise industries.
• Political goals - Détente was seen as a way to legitimise Soviet control over Eastern Europe by securing Western recognition of post-war borders.
• Strategic stability - Reducing the risk of nuclear confrontation with the United States was a key driver, as both superpowers recognised the dangers of escalation.

Key agreements during détente

• SALT I (1972) - The Strategic Arms Limitation Talks resulted in the first major treaty limiting strategic nuclear weapons, marking a step towards arms control between the superpowers.
• SALT II (1979) - This follow-up agreement aimed to further restrict nuclear arsenals but was never ratified by the U.S. Senate due to rising tensions after the Soviet invasion of Afghanistan.
• Helsinki Accords (1975) - Signed by 35 nations, these accords recognised post-World War II European borders, providing the Soviet Union with the territorial legitimacy it sought, while also committing signatories to human rights principles - a point of contention given Soviet domestic repression.
• Trade and cultural exchanges - Détente facilitated increased trade, including Soviet access to Western grain and technology, alongside limited cultural exchanges to ease ideological hostilities.

Limitations of détente

• Continued military build-up - Despite agreements, both sides maintained significant military growth, with the Soviet Union developing new weapons systems, undermining the spirit of détente.
• Proxy conflicts - The superpowers continued to support opposing sides in regional conflicts, such as in the Middle East and Africa, showing that détente did not end Cold War competition.

Soviet intervention in the Third World, focusing on Afghanistan

Brezhnev's foreign policy extended Soviet influence into the Third World, supporting communist movements as part of Cold War competition. The invasion of Afghanistan became a defining, and ultimately disastrous, aspect of this strategy.

Support for communist movements

• Regions of intervention - The Soviet Union provided military and economic aid to communist regimes and movements in Angola, Ethiopia, and Mozambique during the 1970s, aiming to expand its global influence against Western interests.
• Cold War context - These interventions were driven by ideological commitment to spread socialism and strategic goals to counter U.S. dominance in developing regions.

The invasion of Afghanistan in 1979

• Causes of intervention - In December 1979, Soviet forces invaded Afghanistan to prop up a faltering communist government threatened by internal rebellion and to prevent the spread of Islamic fundamentalism near Soviet borders, which could inspire dissent in Soviet Central Asian republics.
• The Afghan quagmire - The Soviet military faced fierce resistance from Afghan Mujahideen fighters, supported by the United States and other countries, leading to a prolonged conflict with heavy Soviet casualties (estimated at over 14,000 deaths by 1989).
• International condemnation - The invasion drew widespread criticism, with the United States leading a boycott of the 1980 Moscow Olympics involving over 60 countries, and providing covert aid to Afghan rebels, escalating Cold War tensions.

Relations with China and the Sino-Soviet split

While Brezhnev focused on détente with the West, relations with China remained strained, reflecting deep ideological and territorial disputes. This rivalry complicated Soviet foreign policy on another front.

Nature of the Sino-Soviet split

• Ideological rivalry - Differences over interpretations of Marxism-Leninism and leadership of the global communist movement fuelled tensions, with China under Mao Zedong rejecting Soviet dominance.
• Border clashes - In 1969, violent skirmishes erupted along the Ussuri River, a disputed border area, heightening military and political friction between the two powers.
• Chinese rapprochement with the U.S. - China's warming relations with the United States in the early 1970s, exemplified by President Nixon's 1972 visit, alarmed the Soviet Union, creating a triangular dynamic in Cold War politics and isolating Moscow further.

The arms race and economic burdens

The arms race remained a central feature of Brezhnev's foreign policy, as the Soviet Union sought to match U.S. military capabilities. This pursuit came at a significant cost to the Soviet economy.

Developments in the arms race

• Strategic parity - By the 1970s, the Soviet Union achieved rough equivalence with the United States in nuclear capabilities, a status symbol of superpower strength.
• New weaponry - The development of SS-20 intermediate-range missiles prompted NATO to respond with Pershing II missile deployments in Europe, escalating tensions.
• Military spending - Estimated at 15-17% of GDP, military expenditure diverted resources from civilian needs, contributing to economic stagnation and shortages of consumer goods.

Economic consequences

• Burden on society - High defence costs limited investment in infrastructure, technology, and living standards, deepening domestic discontent.
• Contrast with détente goals - The focus on military build-up undermined the economic relief sought through détente, as resources continued to be funnelled into the arms race.

The collapse of détente and Brezhnev's legacy

The late 1970s marked the end of détente, as renewed hostilities ushered in the 'Second Cold War'. Brezhnev's foreign policy left a complex legacy, with short-term gains overshadowed by long-term challenges.

Collapse of détente after Afghanistan

• Impact of the 1979 invasion - The Soviet intervention in Afghanistan was a turning point, prompting the United States to abandon détente policies, increase military spending, and impose sanctions like the Olympic boycott and grain embargoes.
• Second Cold War (1979-1985) - This period saw heightened confrontation, with renewed arms races and rhetorical hostility, as trust between the superpowers eroded.

Assessing Brezhnev's legacy

• International prestige - At its height, Soviet influence reached new peaks with recognition in the Helsinki Accords and expansion in the Third World, projecting global power.
• Domestic stagnation - However, the focus on military and foreign policy priorities neglected internal economic and social reforms, leading to stagnation that set the stage for crises under future leaders.
• Long-term costs - The Afghan war and arms race drained resources, while the failure to resolve tensions with China and the West left the Soviet Union increasingly isolated by the early 1980s.
