EXPLANATIONS BELOW
Concept note-1: -In 1903, the United States negotiated a treaty with Colombia that granted the United States the right to construct and operate a canal for 100 years within a zone six-miles wide across Panama.
Concept note-2: -With the help of the United States, a revolution occurred in Colombia that led to Panama’s proclaiming its independence on November 4, 1903. A scant two weeks later Panama signed a treaty allowing the U.S. to build, own, and control the Panama Canal.
Concept note-3: -Americans knew they needed this to move ships from east to west quickly. If they did that, they would control power because they would control the oceans. The Canal was a geopolitical strategy to make the United States the most powerful nation on earth.
Concept note-4: -Why did U.S leaders decide to build the Panama Canal? To make traveling from different parts of The country easier. A canal across the narrow neck of Central America would link the Atlantic and pacific oceans and cut some 8, 000 miles off the voyage by ship from the west to east coasts of the US.
