Panama, 1989
The United States Invasion of Panama, codenamed Operation Just Cause, lasted over a month between December 1989 and January 1990. Its primary purpose was to depose the de facto Panamanian leader Manuel Noriega, who was wanted by the U.S. for racketeering and drug trafficking. 20,000 civilians were displaced from their homes and the chaos went on for nearly two weeks afterward.
