I am reminded of a chilling observation that was published some time ago at zFacts.com:
Bush's job approval rating gained 33% and 14% from declaring war on “terror” and war on Iraq. Capturing Saddam gave him another 6%. Killing Al-Zaqarwi seems to have helped. Verbal heroics for September 11 may help. He needs another approval-rating boost now more than ever, and he is talking of war with Iran. From past experience, it appears that two weeks before the November elections would be the most effective time for such an adventure.
