With the threat of a veto hanging over its head, the National Defense Authorization bill heads to the House floor today for debate. Among the provisions are several dealing with the question of a nuclear weapons armed Iran, and what the United States should do to avert a crisis, prepare to handle the threat, or eliminate the threat altogether.

The Obama administration’s recent focus on finding a compromise to allow the Iranian regime to maintain some enrichment capabilities “for peaceful purposes” distracts from the underlying nuclear threat at hand.

The urgent threat posed by the growing Iran/Hezbollah network in Latin America finally captured the attention of a national audience Tuesday evening as several GOP presidential candidates acknowledged the problem in an AEI-Heritage Foundation debate that aired on CNN. AEI’s Venezuela-Iran project has documented this growing problem.

The dispute over Iran’s controversial nuclear program has reached crisis point. Despite increasing foreign sanctions in recent months, Tehran is continuing its nuclear work, refusing to cooperate, and has indeed tripled its monthly production of higher-grade enriched uranium.

Talks aimed at resolving the Iranian nuclear weapons threat will again resume this Friday. In Seoul late last month, the President reminded Iran that it must act with “‘urgency.” “There is time to solve this diplomatically,” Obama enthused. “It is always my preference to solve these issues diplomatically. But time is short.”

Iran's threat to close a vital international waterway if stricter sanctions are imposed on Iranian oil exports is more than just bellicose and provocative. It is also a test of U.S. will and commitment in the Persian Gulf at a time when our role in the region is changing.

Obama's irresolution and inaction could well make a nuclear Iran his most lasting legacy.
