Glenn Greenwald asks whether the President will feel the need to go to Congress before nuking Iran. In a nutshell, here's his answer:

But does it really matter what any of us, pundits included, have to say about Iran? We are all running around engaged in a debate about how best to approach this situation, presumably laboring under the assumption that we are going to collectively decide this democratically, as a nation. But if the war-mongering radicals in the Bush administration convince The President that some sort of surgical strike, military attack or, decapitation assault against Iran is something we ought to do, will the Administration think that it needs any sort of Congressional authorization to engage in whatever war actions it desires? Very doubtful...

So we can have all the lofty and vigorous debates we want over whether a military offensive against Iran is desirable, prudent, disastrous, crazy, etc. But ultimately, nothing we think - or our representatives in Congress think - really matters, because these decisions, under this administration, are "for the President alone to make." We could refuse to authorize this military offensive, or even enact legislation banning it, and none of that would matter in the slightest. It's worth remembering that in our country today, the President is the "sole organ" in all such matters, and he has full, limitless, and un-limitable authority to do whatever he wants.

If the administration really resolves internally - whether for political reasons or bloodlust or some crazed Steyn-like beliefs or any combination of those or other motives - to attack Iran, is there any doubt that they will do that no matter how much opposition there is? One thing is clear - they believe they have the power and authority to do that unilaterally, and that they need no further authorization of any kind beyond the President's will.
