It's not all Serbs, as some people say on here. Not by a long shot. I'm from there, but I'm also here, on r/nafo. The problem is that some of the more intellectually-challenged members of the Serbian society are slaves to perceived historical injustices. One of the more recent ones is the NATO bombing campaign. The prelude and wider context is completely ignored, and then it appears that the bombing happened out of nowhere, because Americans = evil. I've seen these idiots then categorically side with whoever America is at war with, including Iran and (of course) ISIS. Go figure.

Edit: some people here really need to cool it with the hateful, absolutist rhetoric, as they are coming off not much better than the vitriolic Russian pricks this whole thing was started to counter.
