"The Nuclear Nonproliferation Treaty is arguably the most popular treaty in history: except for five states, every nation in the world is part of it. For more than three decades, it has helped curb the spread of nuclear weapons.

Since 9/11, however, and especially in the last several months, the viability of the treaty has been called into question. Some say it is obsolete. Others say it is merely ineffective. In support of its argument each side cites the situation in Iran, which has been able to advance a nuclear weapons program despite being a member of the treaty."
