It is really funny that the treat the US has made against Spain is to remove a large military base in either Spain or Germany. The US currently has two facilities in Spain namely some aircraft in Moron and a naval presence in Rota. Moron is a small base for the US. So the only one they might close in Spain is Rota, which is a naval base close to the Strait of Gibraltar. The US Navy will be pissed, if they loose that base.
So the US, if the military can do anything about it, will close a base in Germany.

Die Bundeswehr soll doch wachsen und braucht dafür mehr Stützpunkte. Da wären die der Amis doch super für.
