Sane people try to avoid using nukes, by definition, especially in a first strike. Even with exceptional provocation, it's impossible not to consider first use a war crime.
In Bush's case it's just one more to add to the list. And this most supine of so-called Democratic Congresses will very likely stand idly by.
A nuke attack on US soil would be a godsend for Bush. Suddenly it's a real war, which means he gets to suspend the constitution, and the rest.
There's no real down side for him. At worse he gets to blow some shit up. At best he gets to be Dictator in Chief.
Unless someone from the Pentagon marches into the Oval Office with a gun and drags him out, he has nothing to lose and a whole lot to gain.
Ah, there might be hope if there actually was an opposition party in the US.
Alas, there isn't. Fai de bèn a Bertrand, te lou rendra en cagant
When Congress was controlled by the Republicans Bush got to do everything he wanted as soon as he wanted. Now that Democrats have the majority they will fret and talk and quibble and then let Bush do what he wants.
The difference is crucial.
