The United States Invasion of Panama, code-named Operation Just Cause, was the invasion of Panama by the United States between mid-December 1989 and late-January 1990. It occurred during the administration of U.S. President George H. W. Bush, and ten years after the Torrijos–Carter Treaties were ratified to transfer control of the Panama Canal from the United States to Panama by 1 January 2000.
