He also criticized the Rambouillet Agreement, a proposal signed by Albanians but rejected by Serbs, which called for an autonomous Kosovo still under Serb rule.

"America forgot to pressure both sides to create an agreement they [Albanians and Serbs] can both live with," Berg said.

Hannum explored two questions: the legality of the bombing under NATO laws and the value of military action. He answered no to both points.

"If a situation is sufficiently bad," intervention is justified, he said. However, Hannum said the facts in Kosovo do not justify NATO intervention.

He did not deny that there were war crimes. However, "up until March 23 [the day before NATO bombing began], the highest estimate I have seen was 2,000 killed, mostly Albanians, but some Serbs as well." This, however reprehensible, "doesn't justify the war," he said.

"We don't know how to get [to the end] from here," Hannum said. "NATO has dug us an awful big hole."

During the end of the panel, Hannum further addressed the war crimes and human rights violations in Yugoslavia.
