The Strategic Arms Reduction Treaty, or START, signed by President Obama and Russian President Dmitry Medvedev last April to replace the previous treaty which expired a year ago, is now at risk of being stalled by Republicans in Congress. The ostensible issue is mainly procedural—GOP leaders assert that other items on the agenda of the lame-duck Democratic majority have left too little time to debate the pact in the remainder of this session—but Obama supporters charge that the Republicans are simply hell-bent on thwarting the president. Yet as Cathy Young explains, START is a Cold War relic that has no business being an American priority.
