No, members of that army were by US documents seen as terrorists. It means that they killed many innocent civilians and state officials of Serbia. Then suddenly, US stance changed and same people started to be seen as freedom fighters. Go just google on Shquiptar (Albanian) UCK or KLA. Those same people formed then Kosovo police and now forming Kosovo army. Many are also ISIS veterans.
Also, Kosovo isn`t sovereign state no mater that US and some other countries recognized Kosovo. Kosovo isn`t member of UN and isn`t recognized by most of UN member states. Kosovo isn`t member of Interpol and UNESCO. Most importantly, there are ongoing negotiations in Brussels regarding status of Kosovo. Its dialogue between Belgrade and rogue government in Kosovo. If Kosovo is independent, Serbia wouldn`t be asked, don`t you agree? And Serbia is asked because Kosovo was by NATO (in military intervention) taken from Serbia and because of UN resolution 1244 (which resulted from signed truce between sides in conflict, NATO and Serbia) that see Kosovo as Serbian province under UN protectorate. By resolution 1244 Serbia do have right to have up to 1000 soldiers on Kosovo if local Serbs are threatened but, Serbia agreed to talk, instead to increase tensions.
As you see, some others (Albanians, NATO, ISIS and EU) don`t feel necessity to avoid tensions.Vucic: I'm convinced there'll be no war

"I also think that Jens Stoltenberg's message was good and I hope they will understand that in Pristina. .............. many people are trying to make them see reason, .............. important that the international community also understands who wants peace.
