Since the USA is a member of NATO, NATO is far superior. NATO _without_ American support would be a pushover to the Russians. A big part of that is that NATO is overreliant on American power.

Well yes and no. NATO was formed after WWII as an alliance against communist agression of countries in Europe that considered themselves allies of the United states. The communists formed the Warsaw Pact which was the communist countries that condidered themselves aligned with Russia to protect themselves from aggression by the west.

Today they are many and various, but the most important ones are the other members of NATO.
