Another concern is whether the Kosovo Liberation Army will abide by the peace agreement. KLA Cmdr. Ramush Haradinaj told The Associated Press that while the KLA is "still basically at war" with the Serbs, his men will disarm as long as KFOR controls the province.

But as Serfaty put it, "The KLA believes it has accounts to settle based on the Serb brutality of the past 75 days." Seeing what the Serbs have done to Kosovo could rouse the KLA to seek revenge.

Rubin says that if Yugoslavia becomes "an embittered, pariah state, it could engage in covert actions like planting car bombs" that could make life even more difficult for Kosovo's ethnic Albanians.

Thus the need for peacekeeping troops, although how long they will be required is uncertain. The U.N. peace plan calls for a 12-month deployment that can be extended indefinitely.
