START II (Strategic Arms Reduction Treaty) was a bilateral treaty between the United States of America and Russia on the Reduction and Limitation of Strategic Offensive Arms. It was signed by United States President George H. W. Bush and Russian President Boris Yeltsin on 3 January 1993, banning the use of multiple independently targetable reentry vehicles (MIRVs) on intercontinental ballistic missiles (ICBMs). Hence, it is often cited as the De-MIRV-ing Agreement. It never entered into effect. It was ratified by the U.S. Senate on 26 January 1996 with a vote of 87-4. Russia ratified START II on 14 April 2000, but on 14 June 2002, withdrew from the treaty in response to U.S. withdrawal from the ABM Treaty.
