It's never too late. Is it too late for Spain too keep Cataluña in their borders? I only know that majority of western countries was very unfair to Serbia, and Serbian people in general in last two decades. Does we made many bad things on that period? Yes we did. But does we made worst things than Germany in WWII? Or British Kingdom on their colonies? Or Franco's regime in Cataluña? Or Turks against Armenians? I don't think so. Americans killed millions of people in Vietnam, Iraq, Afghanistan, Korea, Libya.... in last 50 years and for many people they are still bastion of freedom and democracy. Nazis killed more than one million Serbs in last world war and nobody calls all that crimes as genocide, but majority western medias call Serbs as genocidal nation for eight tousand muslims killed in Srebrenica (don't get me wrong, Srebrenica was the biggest shame in all Serbian history and all responded for it pay price for.that awfull crimes).
So fight for Kosovo is not over abd it is not too late for changing reality.
