Taken separately, each of his comnents is not really a declaration of war. However, he makes a lot of them, and I think it's getting to the point where Israel will soon be able to make the case that putting them all together, Iran has indeed declared war on it, and can justify a first strike.
Having said that, I always have this comment in mind: "Unilateral Israeli action, without provocation from Iran, could unleash a diplomatic, economic and military backlash such as the Jewish state had never witnessed since 1948, Mr. Sharon argued."I interpret that to mean military provocation. Regardless, Israel will indeed pay a heavy price for a first strike if they should make one.
The US should be the one to do this, but last night I saw a Democratic Rep saying there is no way the Pres could get approval for military action against Iran with Rumsfeld as SecDef, Bush had no credibility (lied over Iraq), blah, blah. Maybe that was just bluster -
So it will be the Dem's a$$es in a crack if they start dealying tactics so that the President's hands are tied in dealing with Iran and then Iran gets stupid and shoots off a nuke.
Bush has already consulted with Congress about this, even with at least one democrat. Maybe he got what he needed.
