Dropping an atomic bomb doesn’t happen as fast as it does in the movies. There’s no room with a red, shiny “nuclear button” primed for the pressing. But in the U.S., launching a nuclear weapon does depend on just one trigger finger: The President’s.

Peace builders, activists, and congressional leaders have tried unsuccessfully to take away this unilateral ability since the Cold War, when nuclear war with Russia felt imminent daily. Now, the threat looms again, as tensions between North Korea and the U.S. simmer—and a new group of local legislators are taking the lead.

A broad coalition of representatives, delegates, and state senators from eight states (California, Georgia, Vermont, Maryland, Illinois, Massachusetts, Minnesota and Iowa) have begun pushing resolutionsthat put additional pressure on Congress to stop the president’s first-strike powers. And cities such as Northampton, Massachusetts; San Francisco, California; Santa Fe, New Mexico; and counties across Washington State have drafted local resolutions of their own.
