Obama Wants to Eliminate Nuclear Weapons

In the aftermath of yesterday's launch, the UN Security Council failed to condemn North Korea. But in Prague yesterday, President Obama said it's the responsibility of the US to lead the way to nuclear disarmament. He pledged to take what he called “concrete steps toward a world without nuclear weapons.” Daryl Kimball is Executive Director of the Arms Control Association, which advocates what it calls “practical solutions” to eliminating weapons-related security threats.
