We did, indeed, occupy Germany, in toto and officially and nominally, until 1955.
We did, indeed, occupy Germany, in large part, and de facto, from 1955 to the 1965-1966 timeframe, as we got the Germans re-started on the road to achieving a credible military once again.
We did, indeed, occupy Germany, as a large military presence on the soil of an ally, from 1965-1966 to the 1994-1995 timeframe, as a credible counterweight to the Soviet threat, and at the continued desire and request of most of our friends.
We began withdrawing from Germany in the 1994-1995 timeframe, so that by the 2004-2005 timeframe, we had a very minimal presence there (45-50,000, total, from all branches of the US Armed Forces), compared to the quarter-million or half-million of bygone years; with far more bases closed-up than still open; more like a supplement and time-buying force to supplement the German's own military strength.
We have very few bases left there by now - having sadly laid-off, for good, hundreds of thousands of local Germans providing long-term support for those US bases - and, still have no more than about 45,000 on German soil, from all branches.
We came - we conquered - we occupied - we fed - we clothed - we helped - we rebuilt - we made friends - we protected - we closed-up shop and left for home - we kept a few thousand folk on hand, in support, and in friendship.
Very few conquerors throughout history have ever conquered, occupied, rebuilt, made friends, protected, then left under their own power.
We did.
We did what was required of us by circumstances and our own interests and those of a free Europe at the time we did them; no point in second-guessing ourselves; nor allowing ourselves to be overly put-out by latter-day Revisionists amongst the Europeans.
Had we not been there in-strength for 50+ years after WWII, all of Europe would be Soviet territory; there would be no European Union; nor independent constituent member states, and there sure-as-hell would not be a gaggle of Free Thinker pissants playing tag with the needs and demands of yesterday, in a slovenly attempt to revise history and paint us as some kind of Bad Guys in this context.
The Free Germany of today was born and grew to maturity under the American Shield, which we held over their heads both out of self-interest and out of a genuine desire to protect them and to help them on their way to rejoining the community of nations as decent folk.
Bad-Guy Occupiers?
Pfffffttt !!!!
