"fully armed"

Right there you start going astray, a lot of them are doing logistics of one type or another, including our largest overseas military hospital, the top level hospital for serious GWoT theater injuries.

More directly, it would all depend on why they were there.

They are nevertheless armed among other things with nuclear weapons.

Those aren't the nukes that Germany would have to worry about.

The U.S. attacking Germany is even more paranoid than chem-trail mind control agents, I'm just throwing that in to go along with the hypothetical.

It doesn't take an attack for there to be problems. Accidents, leaks, contamination, poor behaviour and violence by troops etc is somewhat more likely. That and the external appearance of supporting what ever the stationed troops are up to (often related to regional/nearby wars etc).
