war protesters after camping near Bush's Crawford, Texas, ranch, where he is on vacation, urging him to bring U.S. troops home. More than 1,800 U.S. troops have been killed in Iraq and thousands more wounded. The Bush administration justified going to war in Iraq in 2003 by saying it posed a threat because of stockpiles of weapons of mass destruction. None have been found. Critics say Iraq had nothing to do with the Sept. 11, 2001, attacks on New York and Washington and that the administration has tried to tie Iraq to terrorism since the war to justify its actions. "In a few weeks, our country will mark the four-year anniversary of the attacks of September the 11th, 2001. On that day, we learned that vast oceans and friendly neighbors no longer protect us from those who wish to harm our people," Bush said. "And since that day, we have taken the fight to the enemy," he said. "We're fighting the terrorists in Afghanistan, Iraq, and around the world, striking them in foreign lands before they can attack us here at home," Bush said. --More 2100 Local Time 1800 GMT
