You cannot negotiate with a bully. The EU should have never backed down so easily before. I hope someone will soon find some balls and not let the US walk all over everyone
You can and you should, in order to make your case known, it's simple politics. Huffing and puffing while drowning in moral indignation isn't much different from the other side's approach. And don't jump the gun just because of some silly post somewhere on silly soc media.
I have never seen an official EU statement about US-EU-NATO relations that actually makes sense. What I see is kicking the ball back and forth moving in the same general direction.
