The Intermediate-Range Nuclear Forces Treaty required that both the United States and the Soviet Union destroy their ground-launched ballistic and cruise missiles with the range of 500 to 5000 kilometers, as well as the missiles’ launchers and support structures. This was to be met three years after the Treaty gets entered into force. As the Soviet Union reached nuclear parity with the United States and started vamping up the qualitative element of their missiles, this Treaty helped pacify the arms race between the United States and the Soviet Union. Several proposals were made between President Reagan and General Secretary Gorbachev. When the Soviet Union dissolved, the United States sought full implementation of the INF Treaty with twelve former Soviet republics.
