Dr. Chris McDonald, professor of political science, will provide a presentation on “Unraveling Rule-based World Order” for the World Affairs Council of Central Illinois on Wednesday, May 1, 7 p.m. at the Illini Country Club. The program, co-presented with Dr. Roy Wehrle, will describe our changing world as we move out of the 75 years of peace among the major nations, ending colonialization and remarkable economic prosperity, into a new epoch of history where previous behavior of countries is breaking down, security is threatened and the future will be changed. The presentation is free and open to the public. Reservations are not required for the presentation.
