This is because the Constitution gives the Senate the power to advise and consent on matters related to foreign affairs, including the making of treaties with other nations. The Senate's role in the treaty-making process helps ensure that the United States enters into international agreements that are in the best interests of the country and its citizens. The Senate does not have the sole authority to approve or reject other matters, such as overseas trade negotiations, government projects, or security legislation. These types of decisions are typically made through a combination of legislative and executive branch actions
