As it pertains to military, just wait a few years I think.
While I applaud the strides the EU is taking to decouple militarily, it's still a long ways away from replacing the security umbrella provided by the US military. The EU doesn't even have a single command and control structure (although NATO provides a lot of interoperability between European militaries). It's no knock on Europe's efforts--it's just that the dependency on US military was almost a century in the making--it's not going to be undone overnight. But Europe is moving in the right direction--I just hope Europe stays the course and continues to take it seriously.
You mean decades; especially if they keep up waffling.
The last three times that Europe had a large independent military force(s), things didn't end so well for the world.
International commerce and business and shared democratic norms are a fscking good things. We have lost the people who learned that the hard way, and they are being replaced with people who have never read a history book.
