Technically that doesn’t matter at all because all through the cold war West-German and US interests were very tightly aligned (and when interests diverged a bit the US did give West-Germany enough freedom, though they hardly ever diverged much).
I mean, West-Berlin was most certainly occupied until 1990. It’s just that that was an occupation hardly anyone had a problem with.
The US still has some of its largest overseas bases in Germany; see http://militarybases.com/overseas/germany/
The Japanese could certainly ask us to leave, and we would. But they don't, because except for a vocal minority they do want us there.
And Afghanistan is a war zone. I wouldn't consider that anything but an occupation. Which, I might add, they brought on themselves, so I don't have much sympathy.
Nonsense. That's as clear a case of self defense as you're going to find.
(I just googled it and I see it's deactivated on april 1st 2013 actually)
Interestingly, though, Germany never signed a peace treaty with the US. It only signed a "cease-fire" with the US to end the war. :)
The US military has a policy of being forward deployed around the globe, so it negotiates agreements with may countries around the world to station troops in strategic locations.
The military bases are there as a result of legal agreements and treaties, not because they would forcibly resist any attempts to expel them, and there is no sentiment in the US whatsoever to change that policy and begin fighting to establish bases in friendly countries.
For a parallel, look to Uzbekistan where the US operated an airbase after 9/11. In 2005, there was a massacre by Uzbek government forces, and the US said there ought to be an international investigation. Uzbekistan replied by rescinding the agreement for use of the airbase, and the US left. No shots were fired.
