Europe, espeically Germany, who has been keeping the EU afloat had a kind of obsession with Iran and was hoping to profit big time from the Iran deal but now finds itself in a conundrum.
The Iran Deal fallout moves Germany and the EU closer into Russian orbit and all of this puts America at a crossroads. As the global economy is being unraveled, America must learn to be less dependent on trade with its enemies such as China and Russia, etc. For the most part it has more than enough potential to do this. We have more oil underneath our feet than we know what to do with and we have the ability to feed ourselves unlike any other country on the planet but we almost have to be forced to be weened off of the global economy and back onto the good old American economy. The globalists had been successful in getting us to be completely and totally dependent on the global economy and it proved to be a disaster. Trump is bringing America back to reality and in a good way even if it hurts in the short term.
