MY TEACHER WILL BE CHECKING FOR SIMILARITY AND PLAGARISM.Questions 1. Should the United States seek to tighten its economic grip on Cuba? If so, why?From a practical standpoint, most would argue that without the cooperation of the rest of the world, there is little left that the United States can do. Further, given that China is now a member of the World Trade Organization (WTO) and nations like Vietnam are trading with the United States, the Cuban embargo gives the appearance of cold war relic that is no longer relevant in todays world. However, given the consensus that Cuba consistently violates human rights, the continuance of U.S. trade sanctions against Cuba is consistent with U.S. policy. In addition, Cubas expropriation of American property without compensation is internationally recognized as unacceptable behavior; thus, retaliation can be seen as an appropriate response. Finally, there is the continuing argument that if the Cuban economy can be further weakened, the Castro brothers may at last be overthrown
