The 1987 Intermediate-Range Nuclear Forces (INF) Treaty required the United States and the Soviet Union to eliminate and permanently forswear all of their nuclear and conventional ground-launched ballistic and cruise missiles with ranges of 500 to 5,500 kilometers.
The treaty marked the first time the superpowers had agreed to reduce their nuclear arsenals, eliminate an entire category of nuclear weapons, and utilize extensive on-site inspections for verification. As a result of the INF Treaty, the United States and the Soviet Union destroyed a total of 2,692 short-, medium-, and intermediate-range missiles by the treaty’s implementation deadline of June 1, 1991.
Despite its name, the INF Treaty covers all types of ground-launched cruise and ballistic missiles — whether their payload is conventional or nuclear. Moscow and Washington are prohibited from deploying these missiles anywhere in the world, not just in Europe. However, the treaty applies only to ground-launched systems. Both sides are free to deploy air- and sea-launched missiles within the 500-to-5,500-kilometer range.In 2014, US has alleged that Russia violated the treaty and it has deployed the non-compliant missile. Recently, US announced its withdrawal from the treaty. USA Congress approval for the same is yet to be taken.
