Congress has defeated a request by the Bush administration to fund research and the possible development of a new family of nuclear weapons. The Chicago Tribune reports that arms control advocates are hailing the rejection as one of their biggest successes in more than a decade. Congress’ new $388 billion spending bill eliminates funding for the nuclear “bunker buster” as well as other “advanced concept” tactical nuclear weapons. Congressman Rep. Ed Markey of Massachusetts said, “This is the biggest victory that arms control advocates in Congress have had since 1992, when we were able to place limits on nuclear testing. If we are to convince other countries to forgo nuclear weapons, we cannot be preparing to build an entire new generation of nuclear weapons here in the U.S.”
