Hans Blix at McKendree College

Hans Blix, the former UN weapons inspector, visited Lebanon, IL to be a part of McKendree College’s Distinguished Speaker Series.

Blix discussed the search for weapons of mass destruction and his disagreement with U.S. and British government’s choice to go to war over the weapons.

Along with a team, Blix made 700 inspections in 500 sites in Iraq and found no sign of the weapons.
