In June 1992, President Bush and Russian President Boris Yeltsin signed a "framework agreement" (1) in Washington that provided for the complete elimination of all multiple-warheaded land-based intercontinental ballistic missile (MIRVed ICBM) systems.
For instance, when the US reacted to North Korea's 2006 nuclear and ICBM tests by reinstating the six-party talks in the hopes of appeasing Pyongyang, Iran learned that by exhibiting an interest in engaging the US on its uranium enrichment program it could gain valuable time.
"What is more, if any U.S. mobile ICBM is going to run into problems on budgetary grounds, it is the Midgetman single-warheaded missile, " Gaffney said.
