According to Bush, a nuclear armed Iran threatens us with WW III. This would apparently happen when the US attacked Iran and Russia or China attacked us, causing us to attack Russia or China, all of which, in Bush's view, would be referable to allowing Iran to assume the same nuclear-armed Islamic status as Pakistan occupies today.
Or does he mean that a war between Iran and Israel would be a world war?
We'll never really know, because Bush is insane.
Just another 15 months, folks, just another 15 months.
