US has the capability to replace most of the imports in time.
So basically you are going to change european crap for american crap less cheaper, but in the proces american economy is going to reactivate, money is going to move, jobs are going to be created, investments are going to be made. The only cost that you are going to pay is that some crap is going to cost a little more.

For the EU is basically losing a market, no more money, no more place where to put all the crap, no more crap to be made mean less jobs to have with means more niggers with nothing to do except to rape girls in the streets, etc.
