Nuclear Detectives

Updated: March 14, 2011

You're heard the phrase, "weapons of mass destruction" thousands of times, but how much do you really know about nuclear weapons and the politics surrounding them? Though there's been a Comprehensive Test Ban Treaty on nuclear bomb testing in the past (meaning countries are not allowed to test weapons of mass destruction), North Korea tested two nuclear weapons in May 2009, sparking fear and controversy across the globe.

Last week, however, the Obama administration unveiled a new nuclear weapons policy that rules out the use of nuclear weapons against non-nuclear nations that have signed the treaty. And this week, the President will meet with leaders from 47 countries at a nuclear proliferation summit in Washington. This is big news because it's the largest gathering of leaders on this, or any, topic since the founding of the United Nations in 1945.

The goal of the summit? A big priority is finding ways to work together to make sure a terrorist organization is unable to set off a nuclear weapon any place in the world. For more on the facts about nuclear energy...and weapons, take the quizzes below.
