Serbia is in the process of rebuilding itself, and in the next 75-200 years the time will once again present itself when Serbia can re-take control of its southern province.
In the meantime there are great documentaries like this one, and other wonderful Serbian myths to pass on to future generations of Serbs that will assure that not only will Kosovo remain Serbia, but in the future there will be no chance of another land grabbing attempt by the Albanians.
They haven’t got the forces. They would need air support to establish control of the region. This they haven’t got. One third of the then combat aircraft of Yugoslav Air Force was destroyed in 1999 and it hasn’t been replaced. They simply don’t have the capability to force the current KFOR forces from their positions and to hold the ground. The Serb forces if they ever attempted to move into Kosovo would simply be forced, as in 1999, to disperse and conceal their armor from NATO air power. It would render their forces completley ineffective. Kosovo is lost forever. Any attempt to re-establish control over the province by military force is always going to be seen as an act of agression. Nobody is going to come to the support of the Serbs. Even in 75-200 years from now the situation won’t have changed. No amount of day dreaming is going to chance that.
