More than 100 years after the construction of the engineering marvel that linked the Atlantic and Pacific oceans — and 25 years after the canal was returned to Panama by the US — the Panama Canal faces renewed intimidation from US President Donald Trump.

During Monday’s inauguration, Donald Trump repeated his threat to retake the Panama Canal. The United States controlled the waterway since the early 20th century, but in 1977 President Jimmy Carter signed a landmark treaty to give Panama control of the canal.

We're taking it back.' Trump inauguration speech claim that the U.S. will regain control of the Panama Canal spurs immediate reaction in Panama.

U.S. President Donald Trump’s insistence that he wants to have the Panama Canal back under U.S. control is feeding nationalist sentiment and worry in Panama, home to the critical trade route and a country familiar with U.

President Trump again threatened to take control of the Panama Canal, saying in his inaugural address, “We’re taking it back.” Trump has previously threatened to take over of the Panama Canal and take control of Greenland from Denmark.
