I think it is important to distinguish talk intended to appease the public, that currently is very anti-US, from real policies. For example there is lot of talk about sovereignty in the EU, you can even see lot of that here, but so far no real steps were taken. Globalism cannot be reversed, not without some external factor like global cataclysm. And the public opinion on anything, in the age of Twitter et al, change as often as Trump's proclaimed policies.
Truth is, EU countries have not other potential ally that could replace US, especially among themselves. In Poland some groups dream about European army and French nuclear sharing, when first is pure fantasy, and second is even less reliable that the US one.
You can balance however much you want between US and China, but there may be time when you need to choose. As bad as current state of US is, China is an antithesis to everything EU and its democracies say they stand for.
