Bush looking frightened? Tired? Sick?

Georgie Porgie didn't look like himself at this morning's new conference. When I first saw him talking (suspiciously patronizing)to the President of Columbia, I thought "What's wrong? He looks scared. Or on cold medicines or steroids gone amuck. Something's not right. Does he know something we don't know? Has he received a death threat?

Just now we've learned that the Marriott in Islamabad has been bombed to smithereens, with many casualties. Is something up? Is there more going on? Why am I on edge?
