Serbia does not want to join Nato.Yes and did they achieve peace. They did. There was war in the centre of Europe and Europeans wanted Serbia to settle this amicably. They didn't.
You understand context bud? So how many civilians died there?
Compare to Chechnya.
And how many died there.
And tell me which country would you prefer to live in? Chechnya or Serbia which is due to join EU and wants to join NATO.
Yes I'm sure this hurt Serb pride. But war is not the answer in modern Europe.
You are not rational. You prefer a country like Russia which killed many more people in Chechnya to NATO which has a much much better record. You need to be consistent. If NATO is bad for Serbia, Russia is 100x worse for Chechnya.
