Panama on Tuesday celebrated the 25th anniversary of the U.S. handover of the Panama Canal, which president-elect Donald Trump has threatened to take back.

The canal was turned over to Panama on Dec. 31, 1999. For Carter, the deal signified a new beginning of mutual respect and cooperation between the U.S. and Latin America, as he said in his speech in 1978. It also showed “the last remnant of alleged American colonialism is being removed” during a time when the world moved away from imperialism.

For dozens of US tourists watching a cargo ship pass through the Panama Canal, Donald Trump's threat to possibly wrest back control of the waterway is nonsensical.None of those interviewed backed US President-elect Trump in his repeated threats that he could seize control of the canal after he returns to the White House next month.
