Ukraine agreed to transfer its nuclear warheads to Russia and accepted U.S. assistance in dismantling missiles, bombers, and nuclear infrastructure. Ukraine’s warheads would be dismantled in Russia, and Ukraine would receive compensation for the commercial value of the highly enriched uranium. Ukraine ratified START on February 3, 1994, repealing its earlier preconditions, but it would not accede to the NPT without further security assurances.
