Bush keeps revising war justification
President Bush keeps revising his explanation for why the U.S. is in Iraq, moving from narrow military objectives at first to history-of-civilization stakes now.
Initially, the rationale was specific: to stop Saddam Hussein from using what Bush claimed were the Iraqi leader's weapons of mass destruction or from selling them to al-Qaida or other terrorist groups.
But 3 1/2 years later, with no weapons found, still no end in sight and the war a liability for nearly all Republicans on the ballot Nov. 7, the justification has become far broader and now includes the expansive "struggle between good and evil."
