It feels like the Cold War all over again. According to BBC News, Secretary of State Hillary Clinton said that the U.S. is prepared to extend a "defense umbrella" over the Persian Gulf should Iran develop nuclear weapons. During a regional summit in Thailand, Clinton said that although the U.S. was still willing to talk with Iran, the "nuclear clock was ticking." She also called "crippling action" against Iran a possibility. Furthermore, Clinton said that if U.S. bolsters defense of its Gulf allies, "It's unlikely that Iran will be any stronger or safer because they won't be able to intimidate and dominate as they apparently believe they can once they have a nuclear weapon." Over to you, Ahmadinejad.
