Yes, you are playing with words. the US committment was clear and it was for all of Europe. Obviously, there was going to be some place where the troops would be facing each other.
As for PC, you miss the point. You tried to portray Berlin as a solely "American base" which flies in the face of history. I'm sure the British in Berlin.... and particularly the French... would not agree with your assessment. But, hey, it sort of looked better for arguing your position, right?
