The Dilemma of War
The United States is the world's only military superpower, but the conflicts in Iraq and Afghanistan have demonstrated the difficulty in using that power. The U.S. military has an unmatched capability to destroy, but it does not want to cause unintended casualties.
But there is no such thing as immaculate war. The United States faces a dilemma: if it uses its firepower, it will unavoidably inflict unwanted casualties. But if it doesn't use its firepower, it undercuts a principal advantage and arguably exposes U.S. troops to greater risk.
