What were the operational dates for the Panama Peacekeeping Mission?

The operational dates for the Panama Peacekeeping Mission were indeed from December 20, 1989, to January 31, 1990. This mission was initiated as part of a broader U.S. military operation known as Operation Just Cause, which aimed to depose Panamanian leader Manuel Noriega and restore democratic governance. The specified dates reflect the period during which U.S. forces were actively engaged in the mission to ensure stability in Panama and facilitate a transition to a democratically elected government.

The other options refer to different historical events and missions, none of which relate to the Panama Peacekeeping Mission. Each of those dates corresponds to distinct military engagements or peacekeeping efforts that occurred in various parts of the world, but they do not align with the timeline or objectives of the operation in Panama. Understanding the context of these dates is crucial for grasping the significance and purpose of U.S. involvement in Panama at the end of the 1980s.
