George H. W. Bush and Mikhail Gorbachev signed the Strategic Arms Reduction Treaty in the Kremlin’s St. Vladimir Hall. The document ran to 700 pages. Its core mechanism was a verifiable requirement to cut deployed strategic nuclear warheads from approximately 10,000 on each side to 6,000. For the first time, a treaty demanded reduction, not just a ceiling. The counting rules were meticulous, governing intercontinental ballistic missiles, submarine-launched missiles, and heavy bombers. The process would take seven years.
The treaty mattered because it replaced symbolism with surgery. Previous accords like SALT I and II had capped future growth. START I compelled the dismantling of existing systems. It established an intrusive verification regime involving data exchanges, notifications, and twelve types of on-site inspections. Soviet inspectors would monitor B-52 bomber bases in Louisiana; American teams would visit missile factories in Siberia. This transparency built a technical dialogue that outlasted political hostility. The treaty functionally recognized that mutual vulnerability was permanent, and the only rational path was managed drawdown.
A common assumption is that the treaty’s significance was diluted by the Soviet Union’s collapse five months later. The opposite is true. The treaty’s framework provided the legal and verification architecture for the denuclearization of Belarus, Kazakhstan, and Ukraine, which inherited Soviet weapons. Those nations acceded to START I and returned their warheads to Russia. The treaty did not end the nuclear age, but it created a binding and orderly process for scaling it back. Its inspection protocols became the template for all subsequent arms control. The signing in Moscow was not a finale but the establishment of a slow, grinding, essential machinery of subtraction.
