The European Union is thoughtfully European nationalistic
I know that this is a hard concept to grasp, because it is unprecedented. The train of thought behind this question is something akin to this: If something is above the national scale, it must be globalist, right?
Wrong.
The EU was built, precisely, in order to fight the perils and risks that globalism brings with it.
It is an institution devoted to shield the peoples of Europe from the attacks and competition from superstates such as China or global megacorporations such as liberal Amazon and Facebook.
It has been doing a good, albeit flawed job. The EU is the solution to the problems of globalism, not its cause. The EU offers us the only type of protectionism for small European countries that can work in our globalized age: A multi-national, cooperative type of protectionism.
NOTE: this does NOT apply for a hyper-state like the US or China or India - those three can stand completely on their own. And india is technically a union of nations as well
Make no mistake, the EU will put the interests of the European nations that are part of this union, above those who are not. The EU dont give a crap about the world or the global community. The EU will defend its very European interests to the bitter end.
Thats the very opposite of globalism.
