There is other evidence that "ethnic cleansing" was not producing a refugee problem prior to Nato's war if you seek it out. For example, an Oct 2, 1998 LA Times article on the refugee problem states:
======== Secic fled Kosovo province in neighboring Yugoslavia six weeks ago with her husband and their four children, driven from their farm in the village of Ladrovic by fighting between Kosovo Liberation Army rebels and Yugoslav forces. "There was fighting all around," she said. "We were afraid for our children and ourselves. That's why we left."
