The Pro only identifies US military failures; there are also many occasions of US military success. The Opposition case details examples of military success in Panama, Kuwait, and Bosnia. The recent success of Libyan rebel attempts to overthrow Gaddafi is partially attributable to US military assistance. [1] Furthermore, US military strategy is constantly changing and adapting. The rules of international engagement change relatively quickly; when the rise of the Soviet threat rendered isolationism impossible, the US adapted its foreign policy to a bipolar world in which mutually assured destruction was an effective means of preventing direct conflict. The fall of the USSR created a multi-polar world in which MAD became a more complex and less reliable strategy. Today, the US is adjusting to the increasing threat of Islamic terrorism. These constant changes render perfect implementation of military force impossible- this impossibility is not unique to the US. But with constant reevaluation and assistance from the international community, the US can be a reasonably effective peacekeeper.
