The George W. Bush administration's shift from the military option of a massive strategic attack against Iran to a surgical strike against selected targets associated with the Islamic Revolutionary Guard Corps (IRGC), reported by Seymour Hersh in the New Yorker earlier this month, appears to have been prompted not by new alarm at Iran's role in Iraq but by the explicit opposition of the nation's top military leaders to an unprovoked attack on Iran's nuclear facilities.
The reorientation of the military threat was first signaled by passages on Iran in Bush's Jan. 10 speech and followed by only a few weeks a decisive rejection by the Joint Chiefs of Staff of a strategic attack on Iran's nuclear facilities.
