The facts say the opposite. In 1998 & the first half of 99 there were thousands killed of all ethnicities; 860,000 Kosovo Albanians in refugee camps outside Kosovo; hundreds of thousands more internally displaced inside Kosovo; 120,000 homes destroyed; and 800 Albanian schools plus 235 Albanian mosques and 9 Albanian Catholic churches destroyed or damaged. Then in the summer of 99 after the NATO bombardment, the Albanians returned to their looted & burned-out towns in somewhat of a bad mood and destroyed over 100 Serb Orthodox Churches while over 100,000 Serbs fled revenge attacks.
Compare that with:
2002 "There were 68 killings of citizens in Kosovo during the year, compared with 136 in 2001. According to available figures, assailants killed 60 Kosovar Albanians, 6 Kosovo Serbs, and 2 persons of unknown ethnicity."
2003 "During the year, police recorded 72 killings ... of these, 17 involved victims from minority communities (24 percent). There were 13 killings of ethnic Serbs during the year, 7 of which were widely believed to be ethnically motivated."
2004 "Approximately 62 killings occurred during the year, including 20 deaths as a result of the March violence; 11 of the victims were Serbs, including 8 during the March riots. Outside of the March riots, Kosovo Serbs were victims of three killings, three attempted killings, and one serious attack…"
Compared to 98 & 99 for all ethnicities--and the entire decade of the 90s for Kosovo Albanians--Kosovo is now much less of a "hell-hole" than it was when the Serbs were running the place.
Why don't we look at the period 1945 - 1998, or how about just 1968 - 1998?
Didn't see any mention of the terrorist activity 1992 - 1998 in your post, either.
How about the killing of any American troops by Albs?
