That's where "Serbs destroyed my I.D." ploy kicks in. Since 1941 Kosovo Shiptars have expelled more than half a million people from Kosovo province. Many Albanian Shqiptars immediatelly after crossing the border were sheltered by Kosovo Shqiptars and provided with housing, helth care and pensions. All this without being citizens of Yugoslavia.
What we saw during last week (burning Serb houses in order to claim property is very much what happened 1941-45, 1945-48 and until 1989. Even during Milosevic rule illegal immigration was not much subdued (I suspect heavy bribes to police and border units)
Kosovo Shqiptars are criminalized society. The knowledge that crime does pay is the major motor of criminality and major obstacle to prosperity.
Tito's Yugoslavia, Post-Tito's Yugoslavia and Serbia have invested BILLIONS OF DOLLARS into Kosovo to no result.
Eu, UN and international community invested more than $10B with no results. ISraelis have made garden out of desert with less money.
Now, Kosovo became a major European problem. Only fools believe it will vanish by itself once Kosovo is given independence. It will only get bigger.
One need not look any further than Albanian home country, Albania, to see that outlook is not bright.
As long as people live by the motto "crime does pay" they have no incentive to change.
Rspecting private property and laws is the only way out to drain Kosovo cesspool.
