US Secretary of State Hillary Clinton has said that

that the U.S. has a plan to prevent Iranian domination in the Middle East if it gets the nuclear bomb.

"We want Iran to calculate what I think is a fair assessment: that if the United States extends a defense umbrella over the region, if we do even more to develop the military capacity of those (allies) in the Gulf, it is unlikely that Iran will be any stronger or safer," Clinton said during a visit to Bangkok.

Somehow I don't find this reassuring. Reassuring would be, "We will not let Iran get the bomb".

UPDATE: I see Dan Meridor agrees with me.
