Thankfully, we have not been attacked here at home again (although I expect we will some day). But look at it this way: Suppose we had been attacked again, in comparatively rapid succession and in a variety of ways. In your own private reasoning, be honest with yourself and answer this question: What would your attitude be if, instead of 3,000 dead, we suffered 10,000 or more? Would you want the President to sit around dithering with the UN while your life and the lives of your family were in danger, or act decisively to prevent further attacks? That's the question George W. Bush had to face as dawn broke on December 12th, 2001 — and continually thereafter as the anthrax attacks unfolded.
Where one stands on the Iraq War depends on whether one continues to view the world through a pre- or post-9/11 prism.
