Turning point for missile defense

All this week, NPR's Morning Edition is reporting on the current status and the future of the $60 billion anti-missile defense program.  On Monday, correspondent Mike Shuster turns to Ploughshares Fund President Joe Cirincione for answers to exactly what the missile defense program is designed to protect against.  Tuesday, Cirincione tells Shuster that the system simply does not work. "If we were to have a realistic test this year, next year, it would fail. It would fail catastrophically," he says.
