Answer:
START I was a treaty between the US and the USSR that consisted of self-limiting the number of nuclear missiles owned by each superpower. It was proposed by the then US president Ronald Reagan, and finally signed by George H. W. Bush. On the Soviet side the signer was Mikhail Gorbachev. Initially it was simply called START; the name was changed to START I retrospectively when an update of START I was approved.
It was signed on July 31, 1991, five months before the collapse of the Soviet Union, however, it did not enter into operation until December 1994. The treaty established limitations on the number of various types of vehicles and warheads that both countries They could own. But it also affected some of the new dismembered republics of the USSR, such as Belarus, Kazakhstan and Ukraine. Currently, these last three countries have completely dismantled their nuclear capacity.
