When Bush makes it perfectly clear he means to kill Saddam, and then has time elapse before any results manifest, that gives him a perfect opportunity to do a preemptive strike. What does a dying man have to lose? This could be stupidity.
But for those of us interested in deep politics, Saddam's hostilities to the US would give a pretext for invasion. Try and get this idea, not my own to begin with, spread perhaps even to the mainstream media. Whether planned or blundered, Bush needs to be much more careful about this.
