I don't know how much to believe Capitol Hill Blue, which calls itself "The oldest news site on the Internet." I just hope I can believe them. This article says the Bush's advisors, including Colin Powell, are telling him that he faces a humiliating defeat in the UN Security Council, with possibly only four countries voting for war (presumably the US, UK, Spain and Bulgaria, aka the axis of evil). According to CHB:
As a result, some White House advisors are now urging the President to back off his tough stance on war with Iraq and give UN weapons inspectors more time.

"We have no other choice," admits one Bush advisor. "We don't have the votes. We don't have the support."

Let's hope CHB is right, and that W at least listens to somebody.
