Let's not forget we have one heck of a domino effect happening here.
When the U.S. created NAFTA under Clinton the idea was to create a more productive North American alliance that would be a win/win for the three countries involved. Whatever you think of the net results of NAFTA one result is clear - it spawned the EU.
The EU was formed in response to NAFTA. And that domino precipitated an overbearing, heavy-handed, group of control freaks located in Brussels. And Germany found itself holding the bag.
Through the years Germany has been afforded the luxury of spending heavily on social programs and almost zero on national defense. This is because the U.S. maintained large bases in Germany, which caused their citizens to constantly complain about the bases. But surprise, surprise, when we closed one of those bases the citizens suddenly changed their tune and screamed bloody murder over the closing.
Today we find ourselves in a situation of possibly closing additional bases in Germany and they are in full out panic mode over the idea. Diverting precious Deutsche Marks away from social programs and into defense is simply a bridge too far for most Germans. The potential of holding two bags is a heck of a scary proposition. It's bad enough to be financing the whole EU on their own but also facing serious cuts in social programs in one huge Nein.
Toss in the ticking time bomb of importing hundreds of thousands of Muslim refugees and the overall result is that Germany is starting to feel the vice tightening around their country. No Way Out is one hell of sticky situation.
