Interesting that you pose a question about Bush's plans in a column about faith, because only those who think of Bush as a god believe this plan will work. Those who have faith in peace, those who have faith in justice, and those who have faith in truth never wanted this war.
As to the issue of a just war, we should only base our judgments on specific acts, not on vague words. The war on drugs turns otherwise law-abiding people into criminals and creates a lucrative but deadly underground business, but the war on poverty wishes to elevate people in accordance with humane standards.
The problem, of course, appears when we discuss WWII. But again, we must review what WWII was that the Iraq war isn't. If WWII was about saving a nation, three continents, and the conscience of the US, the war in Iraq is the exact opposite: The nation we were supposed to help is now suffering even more, the continent we were supposed to stabilize is in total chaos, and the American people who see the way events unfold in their name and with their money find it hard to stare at their collective reflection.
