AP: Bush keeps revising war justification

AP's Tom Raum: 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.'

Republicans seized on North Korea's reported nuclear test last week as further evidence that the need for strong U.S. leadership extends beyond Iraq.

Bush's changing rhetoric reflects increasing administration efforts to tie the war, increasingly unpopular at home, with the global fight against terrorism, still the president's strongest suit politically."
