Okay you might not be aware of this but Congress could have stopped him.
Yes. And shame on them.
They gave him the ability because of false info and promises.
That's possible, but I doubt it. Rather, I think it was sheer cowardice. If it was obvious to me that the info was false, it must have been obvious to many in congress. Incidently, there was plenty of cowardice in the media, too.
Without any support, and indeed active resistance, Congress would not likely have allowed it to move forward.
I admit that the figleaf of support made it easier for congress folk to support their cowardice.
Incidently, on this very day congress is again showing its cowardice, by going for a "compromise" that will allow Bush to use torture (under a suitable euphemism). Shame on them.
