Missile Defences in Europe

I agree with President Obama’s decision to cancel missile defence system plan related to Czech Republic and Poland (See the link below). In my opinion, Europe should take complete responsibilities for its own defense and America should even phase out all its troops from Europe in due course of time. Immediately after World War II there was a need to have a strong American troop’s presence in Europe for its defense. However after the end of cold war and the fact that Europe is affluent, American tax payers should not keep footing the bill for Europe’s security.
