Europe cannot rely on American intervention, irrespective of the grounds. It’s game over.
When I say that’s what it feels like I want you to understand that every time I ask someone who is heavily in the favor of intervening in Europe here in the US, at its core it’s almost always “because these are people like us” argument. In America the whole argument for why we should intervene in Europe relies upon a hidden assumption, the moment you make it explicit, there is absolutely no way defendable (because nobody wants to be called racist and the non-racist position would be to advocate intervening all over the world, a quite unpopular opinion in the US these days).
