What might happen if the president alone did not have the power to negotiate with foreign governments?

If the president did not have the power to negotiate with foreign governments, it could lead to a fragmented and inconsistent foreign policy, as multiple entities might pursue divergent interests. This could create confusion and weaken the United States' standing on the global stage, as cohesive and strategic negotiations are crucial for effective diplomacy. Additionally, the legislative branch could become overwhelmed with foreign policy matters, potentially hindering timely decision-making and response to international crises. Ultimately, it could diminish the efficiency and effectiveness of the U.S. government's ability to engage with other nations.
