Thankfully, the public outrage was so great that Ahmadinejad cancelled his visit.
If he had gone there, it would have been a huge public-relations victory for him in the Islamic terrorist culture. Posters of him at Ground Zero would have appeared all across the world in the radicals' homes with titles like "Ahmadinejad conquers America a second time". Ahmadinejad is a recognized sponsor of terrorism and Iran is a state sponsor of terrorism and also intent on destroying Israel and the U.S.A.
Conservatives should take note that when they really push hard on an issue, they can win against liberals and terrorists. The only hope for keeping America "the land of the free" is for conservatives to come together and push the conservative agenda. Do your part by writing your Congressmen and Senators and let your voice be heard.
