1. Do politicians consider what the public will think when making decisions?
. . . Of course they do!- They know if they buck popular sentiment they will be out of a job in the next election.
2. British intelligence had the same phony reports from the same guy. The fact that every one is drinking the same bad tea doesn't make it good tea.
3. Had it not been for Bush's intervention the CIA expected Saddam would have been soon overthrown anyway. He was widely hated and in constant fear of a revolt- even from his own military. This would have been an even better example for the Iranian people to follow.
