Strategic Arms Limitation Talks 2

SALT II: A Legacy of Détente and Disarmament

The Strategic Arms Limitation Talks II (SALT II), officially the Treaty Between the United States of America and the Union of Soviet Socialist Republics on the Limitation of Strategic Offensive Arms, stands as a significant, albeit ultimately imperfect, chapter in the history of Cold War arms control. Signed in 1979 by President Jimmy Carter and Soviet Premier Leonid Brezhnev, SALT II aimed to curb the escalating nuclear arms race between the superpowers. While it never entered into full force, its legacy continues to shape discussions on nuclear non-proliferation and arms control strategies today. This article will delve into the context surrounding SALT II, its key provisions, the reasons for its failure to be fully ratified, and its lasting impact on international relations.

The Context of SALT II: A World on the Brink

The late 1970s witnessed a complex and volatile international landscape. The Vietnam War's conclusion had left the United States grappling with domestic turmoil and a reassessment of its global role. Simultaneously, the Soviet Union, under Brezhnev, was experiencing its own period of internal stagnation while simultaneously expanding its global influence. This period, often characterized as a period of détente, a lessening of Cold War tensions, was punctuated by periods of heightened anxiety, driven largely by the escalating arms race. Both superpowers possessed arsenals capable of inflicting catastrophic damage on each other, leading to a climate of fear and uncertainty.

The previous Strategic Arms Limitation Talks (SALT I), concluded in 1972, had achieved a measure of success by establishing limitations on anti-ballistic missile (ABM) systems and setting a freeze on the number of intercontinental ballistic missiles (ICBMs) and submarine-launched ballistic missiles (SLBMs). However, SALT I was merely a first step. The development of new weapon systems, particularly the multiple independently targetable reentry vehicle (MIRV) technology, which allowed a single missile to carry multiple warheads, drastically increased the potential for destruction. This, coupled with continued technological advancements and a lack of transparency regarding weapon stockpiles, fueled the need for a more comprehensive agreement.

Key Provisions of the SALT II Treaty

SALT II represented a more ambitious attempt to constrain the nuclear arms race. It built upon the foundation laid by SALT I but introduced more specific numerical limits on strategic offensive arms. Some of the most significant provisions included:

• Limits on Delivery Systems: The treaty established limits on the number of ICBMs, SLBMs, and heavy bombers equipped with long-range cruise missiles. This aimed to prevent the uncontrolled proliferation of these crucial delivery systems.

• Equal Aggregate Totals: A crucial element was the establishment of equal aggregate totals for the number of strategic delivery vehicles. This principle of numerical equality aimed to create a sense of parity between the US and Soviet arsenals, theoretically reducing incentives for either side to engage in an escalating arms race.

• Submarine-Launched Ballistic Missiles (SLBMs): Specific limits were placed on the number of SLBMs each side could deploy, acknowledging their growing importance in strategic nuclear deterrence.

• Verification Measures: While not perfect, the treaty included provisions for verification, primarily through national technical means (NTM) such as satellite imagery and reconnaissance flights. These methods aimed to promote transparency and build confidence in compliance. However, the limitations of verification technology at the time posed a significant challenge.

• Comprehensive Definition of Strategic Arms: SALT II attempted to define precisely what constituted a “strategic” weapon, although ambiguities remained, particularly concerning the definition of cruise missiles and other emerging technologies.

The Failure of Ratification: A Political Earthquake

Despite the extensive negotiations and the apparent progress made, SALT II never entered into full force. Its demise was a consequence of a confluence of political factors, both domestic and international:

• The Soviet Invasion of Afghanistan (1979): This event proved to be a pivotal moment. The Soviet invasion was perceived by the Carter administration and the US Congress as a major breach of international norms and a blatant act of aggression. This dramatically altered the political climate, making it politically impossible for the Senate to ratify the treaty. The perception of Soviet expansionism undermined the spirit of détente and damaged trust between the two superpowers.

• Domestic Political Opposition in the US: Even before the Afghanistan invasion, SALT II faced strong opposition within the United States. Conservative Republicans, led by figures like Senator Henry Jackson, argued that the treaty was too lenient on the Soviet Union and failed to adequately address Soviet military advancements. They expressed concerns that the treaty would disadvantage the US in the long run.

• Technological Advancements and the Arms Race: The relentless pace of technological advancement made it difficult to predict future arms races. The emergence of new weapon systems and the potential for technological breakthroughs rendered the treaty's numerical limitations potentially obsolete even before it could be ratified.

• Lack of Complete Transparency: Even with verification measures, concerns about the accuracy and completeness of Soviet declarations regarding their nuclear arsenal remained. A lack of full transparency fueled mistrust and hampered the treaty's effectiveness.

The Legacy of SALT II: A Continuing Debate

Despite its ultimate failure to be ratified, SALT II had a significant impact on the course of arms control negotiations. It demonstrated that even during the height of the Cold War, meaningful dialogue and arms control agreements were achievable. While the treaty itself never entered into force, many of its provisions served as a basis for subsequent arms control agreements.

Furthermore, SALT II's legacy extends beyond specific numerical limits. It highlighted the importance of verification, transparency, and effective communication in building trust between adversarial nations. The challenges encountered during SALT II’s ratification process underscored the critical role of domestic politics in shaping international relations and arms control policy.

The failure of SALT II also served as a stark reminder of the fragility of détente and the volatile nature of the superpower relationship. The Afghanistan invasion underscored how rapidly geopolitical shifts could derail even the most painstakingly negotiated arms control agreements.

Conclusion: Lessons Learned and Future Implications

The Strategic Arms Limitation Talks II remains a complex and multifaceted case study in arms control. While it ultimately failed to achieve its intended goal of fully limiting strategic offensive arms, it provided valuable lessons on the challenges of negotiating and implementing arms control agreements in a climate of mistrust and escalating superpower rivalry. Its legacy continues to inform current debates on nuclear non-proliferation, the complexities of verification, and the significance of domestic political considerations in shaping international security policy. The enduring question remains: how can we learn from the successes and failures of SALT II to build a more secure and stable world in the face of future nuclear threats? The challenges posed by the SALT II experience remind us that while arms control agreements can contribute to stability, their success hinges on a complex interplay of geopolitical circumstances, technological advancements, and, critically, a commitment to cooperation and trust between nations.
