Too bad some people forget how hard those times in the past were and the relationship between friends that ended it. Alot of Europeans are still trying to pass on that guilt from the two worst wars in the history of mankind which they were a part of. Its been recognised by many pyschologists and great thinkers for alot of Europeans anti American stance over the years.
We have to remember that Germany hasn't truly been free for a long time either. Talk about gratitude. LOL. The Iron Curtain was more thankful!
