The bigger issue here is that Europe depends way too much on the USA in so many areas. This is not good - you can be constantly blackmailed when you have people such as Trump in charge. I don't think the EU can be fixed, but at the same time I also think the less Europeans depend on outside factors (in particular the USA) the better. Canada kind of showed how to do it. Granted, Canada is also dependent on the USA in numerous ways and most of this is hard to fix (most Canadians live in the south aka close to the USA and trade is primarily done via the USA; security has also been largely outsourced onto the USA and so forth). The sooner people in Canada and Europe get moving away towards more independence from the USA, the better. And more cooperation would not harm either.
