COMMENTARY by Maureen Dowd: In the thick of the war with Iraq, President Bush used to pop out of meetings to catch the Iraqi information minister slip covering grim reality with willful, idiotic optimism. "He's my man," Mr. Bush laughingly told Tom Brokaw about the entertaining contortions of Muhammad Said al-Sahhaf, a k a "Comical Ali" and "Baghdad Bob," who assured reporters, even as American tanks rumbled in, "There are no American infidels in Baghdad. Never!" and, "We are winning this war, and we will win the war. . . . This is for sure. "Now Crawford George has morphed into Baghdad Bob.” Speaking to reporters this week, Mr. Bush made the bizarre argument that the worse things get in Iraq, the better news it is. "The more successful we are on the ground, the more these killers will react," he said.
