As I see it, this war is not so much about Al Qaeda or because of a direct threat to the United States. The United States and its allies is waging war to liberate Iraq from its dictator, bring democracy to the region and eliminate weapons of mass destruction which might do harm to America's allies in the Middle East or (indirectly) reach the hands of terrorist groups. I think this war of liberation it is justified. The Left used to love and romanticize wars of national liberation. They worshipped such figures as Che Guevara who was prepraed to take the revolution worldwide. They loved Cuba for its willingness to send troops to Angola to help the national liberation struggle there. The Left should also like President Bush's idealism and desire to bring democracy to countries suffering under dictatorship. But of course they don't. The far left has always defended tyranny against capitalist democracy.
