Who is responsible for making treaties with foreign nations?

The President is responsible for making treaties with foreign nations because the U.S. Constitution grants this power directly to the executive branch. Specifically, Article II, Section 2 outlines that the President has the authority to negotiate and enter into treaties, but it also requires that these treaties must be ratified by a two-thirds majority in the Senate. This structure establishes the President as the primary negotiator in foreign policy while ensuring that the legislative branch plays a crucial role in the approval process. The distinction is important to highlight the collaborative nature of treaty-making in the U.S. government, with the President effectively leading negotiations but needing legislative confirmation to finalize treaties.
