US Troops In Europe-Why?

Once upon a time, a long, long time ago there was something termed a Cold War between the Soviet Union and the North Atlantic Treaty Alliance. The assumption was there was need for American troops in Europe in order to make clear to Soviet leaders that an attack on West Europe would involve an attic on the United States of America. In 1991, the nation then known as the Soviet Union, collapsed and ceased to exist. The current Russian army would encounter problems fighting Georgia-as it did. The question of the hour is-why are there American forces in Western Europe?

The Cold War ended two decades ago. There is NO  threat from the East. There is NO threat from Russia. Ami, it is time to pack up and Go Home! It is time to end relics from the past.
