Nuclear Options: What to Do About America's WMDs

LOS ALAMOS, N.M. – Pat Sena has a routine: He prays with his wife, he reads, he drives his '97 Chevy pickup through Albuquerque's low-slung outskirts to work. Then, at the office until he heads home, he and his team make sure the U.S. can still – at any moment – blow up the world.

“The way I think of it, I think of myself at my home, my family in my home. It's a rough neighborhood, there are gang members driving by and drive-by shooters, and I'm sitting out on the porch with a big shotgun, saying, 'Don't attack my family because you'll have to deal with me,’” he says.
