This Late Edition examines what the U.S. role in the Bosnia conflict should be when the Bosnian Serbs are overrunning the safe haven of Srebrenica and are on the verge of overrunning another safe haven, Žepa. A report from Sarajevo on the military situation on the ground by Brent Sadler is featured. Richard Holbrooke, U.S. Assistant Secretary of State, joins a discussion on the nature of the involvement of U.S. troops in Bosnia. Three retired generals, Gen. Mackenzie, former UN commander in Bosnia; Crosbie Saint, former NATO commander; and William Odom, U.S. Army, discuss what the U.S. troops would face if sent to Bosnia. Statements by William Perry (courtesy of ABC) on the importance of sustaining neutrality in the peacekeeping missions, and Alexander Ivanko, UN Spokesman, who speaks on the situation in Žepa, are featured. Pictures of Bosnian Muslim refugees from Srebrenica are shown. A discussion on this topic with a panel of journalists, Tony Snow (Detroit News), Eleanor Clift (Newsweek), and Alan Murray (Wall Street Journal), is also featured.
