I appreciate the anti-Ahmadinejad sentiment espoused by John McCain, Michelle Malkin, Bill Hobbs and others. I certainly don’t like the thought of that madman, terrorist supporter and enemy of the United States traipsing around Ground Zero, which remains an open wound. In fact, I don’t believe the Iranian president should be allowed to step foot inside our country to begin with. On the other hand, how are you going to realistically stop him from viewing the site? You can’t prevent Ahmadinejad from seeing an empty space. To our shame, it’s still just a gap in the skyline. How do you prevent someone from seeing nothing? How far can you push him back until he can’t see what isn’t there? How can he defile a sacred monument that doesn’t exist?
