The USA Military Prepares Iran Air Strikes?

I wonder if the military is gearing up for a massive raid on Iran's nuclear program?

Item number one: The USA tests a 700 ton coventional bunker buster near Las Vegas that caused commentary because of the mushroom cloud.

Senior British officials were to meet with military chiefs today to discuss the likely consequences of a military attack against Iran's nuclear program, a senior foreign ministry official said. Some British authorities think an American-led attack, designed to destroy Iran's ability to develop a nuclear bomb, is "inevitable" if its leaders fail to comply with the United Nations' demands to freeze their uranium-enrichment program, said the source, who spoke on the condition that he not be identified….

The source said British defense chiefs think the Bush administration is prepared to conduct the attack on its own or with the assistance of Israel, if there is no other international support. British military chiefs think such an attack would be limited to a series of air strikes against nuclear plants….

However, the British military chiefs are concerned that an attack on Iran would "unhinge" areas patrolled by British forces in southern Iraq, an area mainly populated by Shi'ite Muslims with links to Iran.
