Why exactly would Serbia be at war with all of its neigbours exactly? Do you beleive that a small country surrounded by NATO and militarily neutral (not to mention with a decrepit military) would suddently with no reason join the war on Russia’s and China’s side and start attacking its neigbours, most of whom it views as very friendly? Or do you think that Serbia is some monster just waiting for an opportunity to attack all of its neigbours for territorial gain? The only recent conflicts Serbia had with its neigbors were with two countries, with Croatia, which wouldn’t have happened if a large population of Serbs wasn’t living in Croatia and also didn’t feel like they were being threatened again by the same extremists that had them genocided a generation ago, but those people have for the most part been expelled and ethnically cleansed so there is no reason to have any conflict with Croatia, and Bosnia, where all three sides fought each other and Serbia as a country wasn’t even officially involved, but did support the Serb side in many ways. There is no anymosity towards either Hungary or Bulgaria, Romania is viewed very positively, brotherly even, just like Montenegro, Macedonia and Greece. There isn’t even any strong feeling towards Albania, nobody really cares about it. The only possible conflict areas involving Serbs are Kosovo, because of the illegal seccession and the Serbian minority there, but even in this case the general public opinion about an armed conflict is very negative, and Bosnia, due to Republika Srpska being denied the same right to self-determination as Kosovo, but I don’t see Serbia as a country getting directly involved in any conflict there, it would be mostly internal, unless NATO decides that Serbs there should be prevented by force from being independent if they ever try to do that in the future. So where exactly do you see the danger in being close to Serbia?
