I don't see the Bush Admin having the political capital, or the backing of enough of the nation, to do anything regarding Iran. Thanks to the treasonous left, alot of Americans are already tired of the War on Terror and just want it to end. I get the feeling that those who do support the campaigns in Iraq and Afghanistan do so grudgingly, and would not be at all supportive of going into Iran as well.
Most Americans have very short memories. The only way I see enough of the country getting on board with action against Iran is if there were to be another major strike against us. This is only my opinion.
Opinion understood. Of course, none of us will know for sure until after it happens or not.
There's also the consideration of our troops in Iraq, though.
Iran may strike US forces in the Gulf, maybe with a boat carrying a suicide bomb. I hope its not a nuke.
Unless Congress declares war on Iran, Bush should not act.
