A holiday honoring Panamanians killed protesting the U.S. presence there in 1964 takes on added resonance amid Trump's threats to retake the Panama Canal.

Hundreds of Panamanians marched on Thursday to mark the anniversary of a deadly uprising against U.S. control of the Panama Canal in 1964, with some protesters burning an effigy of President-elect Donald Trump who has threatened to retake the vital global waterway.

Trump's intention marks a rejection of decades of U.S. policy that has prioritized self-determination over territorial expansion.
