Coupled or uncoupled, an equal relationship between the US and the EU is much healthier. Europe should have an economy, military and industrial capacity similar to the US.

While in the current case I agree it is the path that should be taken, ideally I would prefer efficient relations, where people cooperate rather than having to duplicate everything because they don't trust their neighbor (should I make my bread because the baker might decide to poison me?!).

But having educated people everywhere is hard, so some people, because they don't get how some stuff works, they try to abuse friends and allies and make things worse (inefficient) for everybody in the process.
