However, the threat from Iran remains. It might be noted that Iran and Iraq have long been tense neighbors. While some Iraqis may want a continued American presence in the country, it isn't clearly beneficial or necessary. American power in the region should be enough to prevent Iran from provoking any real trouble, and minor problems can be handled by Iraqis. The presence of American troops on the other hand continues to provide fuel to elements that don't like America and don't want to see democracy in Iraq. This fuel makes the country more unstable than it might be otherwise.
