He'll probably attack us directly
We know Saddam has VX. The authorities are checking for bombs and guns at the airports but are they looking for VX? Saddam must surely have agents in the United States and Europe or has been doing some liason with what remains of the Al Queda leadership. He knows that we would respond with our own WMDs so using VX would be his last throw (like blowing up the oil wells in Kuwait).
This is a necessary war but there is a lot being left to chance. I just hope a coup can be organized in time.
