Of course, this is not at all surprising. We all knew he was going to do it. However - Dubya's "my way or the highway" way of managing the country is getting old. No - it has been old for a long, long time.
The best idea I've heard is that Congress should now pass a bill on to The Decider that gives full funding, with no timeline. But - with definite benchmarks. And with funding only guaranteed for, say, two months. So that in two more months, The Decider will have to come back to Congress, asking for more money, and will have to show what progress his administration has made toward meeting those benchmarks.
I agree - The President is constitutionally the Commander In Chief, and Congress has no power to micromanage any war. But - Congress DOES control the pursestrings, and if The Decider refuses to listen to the majority of public opinion, it is Congress' duty to follow the will of the people. Bush's (or rather, Cheney's) theocracy has been pulling us down too long.
