Manning MEMO:
At their meeting, Bush and Blair candidly expressed their doubts that chemical, biological or nuclear weapons would be found in Iraq in the coming weeks, the memo said. The president spoke as if an invasion was unavoidable. The two leaders discussed a timetable for the war, details of the military campaign and plans for the aftermath of the war. The memo also says the president raised three possible ways of provoking a confrontation, including the most controversial:
"The U.S. was thinking of flying U2 reconnaissance aircraft with fighter cover over Iraq, painted in U.N. colours," the memo says, attributing the idea to Mr. Bush. "If Saddam fired on them, he would be in breach".[1]
