START II arms control treaty signed

The START II arms control treaty was a pivotal agreement aimed at reducing the nuclear arsenals of the United States and Russia. It specifically targeted the elimination of multiple independently targetable reentry vehicles (MIRVs) on intercontinental ballistic missiles (ICBMs), which allowed a single missile to carry multiple warheads, each capable of hitting different targets. The treaty was signed by both nations, reflecting a mutual interest in curbing the arms race that had characterized the Cold War era. Although the treaty was ratified by both the U.S. Senate and the Russian Duma, it faced significant challenges in implementation. The geopolitical landscape shifted, leading to concerns about national security and the effectiveness of existing treaties. As a result, the treaty was never put into practice and was ultimately abandoned, particularly after the U.S. withdrew from the 1972 Anti-Ballistic Missile Treaty, which had been a cornerstone of strategic arms limitation.
