Kosova was NEVER Serbia 

Look, if Kosova was in Serbia, Serbia would have never invaded it, and the west would not have driven them out would they. Noel Malcolm's article is precise that in 1912, Serbia occupied Kosova. It was not a liberattion because the 75% then-Albanian majority never welcomes them. It stayed occupied until it joined Yugoslavia in which it and Serbia were federal counties. This is sourced everywhere, so why do Serbo-nationaliosts continuously revert these edits???
