INF Treaty

INF Treaty was a landmark arms control agreement between the United States and the Soviet Union. Signed by Ronald Reagan and Mikhail Gorbachev in 1987, it required the complete elimination of all ground-launched ballistic and cruise missiles with ranges between 500 and 5,500 kilometers. The treaty marked the first time the superpowers agreed to reduce their nuclear arsenals and established an intrusive verification regime, significantly reducing tensions during the final phase of the Cold War.

Background and historical context

The treaty's origins lie in the late 1970s with the Soviet deployment of the SS-20 Saber missile, a mobile system that threatened targets across Western Europe and Asia. This prompted a firm response from the NATO alliance, which approved the "dual-track" decision in 1979 to deploy American Pershing II and BGM-109G Ground Launched Cruise Missile systems while pursuing arms control talks. The resulting escalation, part of the broader Second Cold War, fueled massive nuclear disarmament protests in cities like Bonn and London. Diplomatic efforts, including the Geneva Summit and the Reykjavík Summit, were initially stalled but gained momentum under the reformist policies of Mikhail Gorbachev, known as glasnost and perestroika.

Key provisions and scope

The treaty's core obligation was the verifiable destruction of all existing missiles, launchers, and associated support structures within three years. It covered two distinct classes of weapons: shorter-range missiles, defined as those with ranges between 500 and 1,000 kilometers, and intermediate-range missiles, with ranges between 1,000 and 5,500 kilometers. This encompassed famous American systems like the Pershing II and the Soviet SS-20 Saber and SS-4 Sandal. Notably, the agreement applied only to ground-launched systems, explicitly excluding sea-launched cruise missiles and air-launched cruise missiles, which remained subject to other negotiations like the Strategic Arms Reduction Treaty.

Implementation and verification

A highly intrusive verification regime, unprecedented for its time, was central to the treaty's execution. This included both national technical means, such as reconnaissance satellites, and extensive on-site inspections. The On-Site Inspection Agency was created by the United States Department of Defense to conduct inspections within the Soviet Union, while Soviet inspectors were granted access to American facilities like the Pershing plant in Magna, Utah. Designated missile operating bases and support facilities were subject to short-notice inspections for thirteen years. The physical destruction of missiles was carried out by methods such as explosive demolition, burning, and crushing, often conducted at iconic sites like the Kapustin Yar launch complex.

Violations and withdrawal

Following the dissolution of the Soviet Union, the treaty remained in force with Russia as the successor state. However, in 2014, the Barack Obama administration formally accused Russia of violating its terms by developing and testing a prohibited ground-launched cruise missile, later identified by NATO as the 9M729 (SSC-8). Subsequent diplomatic efforts through the Special Verification Commission failed to resolve the compliance dispute. Citing this violation and the need to counter missile deployments by China, the Donald Trump administration announced the United States' suspension of its obligations in February 2019, triggering a formal withdrawal process completed in August 2019. Russia immediately suspended its own participation, effectively terminating the agreement.

Strategic implications and legacy

The treaty's demise has had profound consequences for global strategic stability. Its collapse removed constraints on the development of intermediate-range systems in Europe and Asia, leading to renewed arms competition. The United States Army has since tested new prototypes like the Typhon and deployed the BGM-109 Tomahawk to allied territories. Russia has fielded additional battalions of the 9M729 and other systems. The absence of the treaty is seen as a significant setback for the broader framework of arms control, which also includes the New START treaty and the Treaty on Open Skies, raising concerns about a new, less-regulated missile age and placing increased pressure on alliances like NATO and the ASEAN regional forum.
