Executive Order 14199 represents a significant departure from traditional US foreign policy, exhibiting strong authoritarian patterns through unilateral action, centralization of power, and the framing of international organizations as adversaries. It raises serious constitutional concerns regarding the separation of powers and the legislative branch's role in foreign policy. The order's potential to erode democratic norms, weaken international cooperation, and undermine the rule of law is substantial. While historical precedents exist for isolationist tendencies, the breadth and aggressive nature of this order suggest a potentially more profound shift in US engagement with the world.
