The 1914 Bryan–Chamorro Treaty attempted to convert Nicaragua into a de facto protectorate, and the U.S. stationed soldiers there throughout Wilson's presidency. The treaty gave the U.S. the exclusive right to build a canal across Nicaragua, in an attempt to prevent a rival power from constructing a canal to compete with the Panama Canal. Although the treaty negotiated under the Taft Administration, Wilson was enthusiastic about completing the agreement. He added language similar to the Platt Amendment in Cuba, whereby the U.S. maintained control. The U.S. Senate rejected that provision and the treaty was ratified in June 1916.
