C) The Constitution supports international order by providing legal procedures for approving international treaties.
The excerpt indicates that the President has the authority to make treaties, but this power is constrained by the need for Senate approval, specifically requiring a two-thirds majority of senators present for concurrence. This creates a system of checks and balances that ensures that treaty-making is not solely at the discretion of the executive branch, thereby reflecting a democratic process. By institutionalizing this procedure, the Constitution enhances the predictability and legitimacy of the U.S. engagement in international agreements, contributing to a stable international order. Moreover, it ensures that international treaties are representative of broader national interests, which can help maintain peace and order on the global stage.
