President Bush spoke to the nation last night to set in motion the next course of action in Iraq. Iowa State University political science professor James McCormick says this is an important step in moving ahead to the next phase.Other wars, included the first Gulf War, ended with the signing of peace treaties with conquered leaders. This time the leaders are either dead, hiding or in custody, leaving a leadership vacuum.He says this makes it different from other wars, and he says the thing to do now is for the president to go on a diplomatic initiative. McCormack says the building of allied support shouldn’t be overlooked. He says it will be critical to get the governance success in Iraq. While the military portion of things went well, McCormack says don’t expect such results with rebuilding. He says Bosnia is a parallel example in which President Clinton says troops would stay there only one year, and they’re still there.
