Treaties are agreements between the United States and other countries. Since the President serves as the head of the nation's foreign affairs, they have the responsibility and power to propose and approve treaties. The Supreme Court is responsible for interpreting the law and does not have the power to propose or approve treaties. While Congress holds the power to ratify treaties, they do not have the authority to propose them. State governors do not have a role in the process of proposing or approving treaties, as foreign affairs fall under the jurisdiction of the federal government. Therefore, the correct answer is the President.
