The war on terror is an abstraction. But the terrorists are real people and they are not all alike. Most of the people attacking our soldiers in Iraq originally had nothing to do with al Qaeda. They have been generated by the policies of the Bush administration. We have been spared a terrorist attack at home but it is quite a stretch to attribute that to the invasion of Iraq. The insurrection in Iraq, however, is a somber reality and it doesn't make us safer at home. Our security, far from improving as President Bush claims, is deteriorating.
