That wasn't the question. What I was going for is the fact that no EU country would wage war with Russia because America wants it so. Yes some will try to start one but it will fail.
You forgot one thing, each and every US president started some kind of war or continued one that was started by his predecessor that was started based upon a lie and misleading US citizens. Current state of politics is that Putin is a bad guy while American president is a saint, i don't think Trump will change the course or will be allowed to do so but i don't think he is stupid enough to start a war on a global scale.
