Personally I hope the European powers ignore American threats of sanctions against their companies, and continue to chart an independent European foreign and economic policies away from the United States.
The American empire is dying, hopefully collapsing soon under the weight of its own internal contradictions, and when that happens I hope the American populace takes back their government and military away from the ruling class that is robbing them, oppressing them, and sending their children to die meaningless deaths in the deserts of the middle East.
