Iran's Nuclear Threat

With the U.S. stretched thin by the war in Iraq, leaders look nervously to Iran, a member of President Bush's infamous "Axis of Evil" whose government is now openly defying warnings to cease its nuclear development programs.

A few months ago it looked as though Iran would halt its nuclear activities in exchange for trade incentives from the European Union. But now all bets are off. The International Atomic Energy Agency has confirmed that Iran is now rebuilding nuclear centrifuges.

An Iran with nuclear weapons would drastically alter the geopolitical landscape of the Middle East. World leaders want to take a stand against Iran, but must tread carefully to avoid igniting a disastrous conflict. The stakes are high as experts now address the possibility of a nuclear Iran.
