Trump's remarks indeed reflect his radical and unique perspective on international affairs. From an economic standpoint, he may believe that resource integration and administrative unification in North America can reduce the costs related to trade barriers, such as the various expenses and cumbersome processes involved in trade agreements and border management between the United States, Canada, and Mexico. However, this notion seriously overlooks the independence and national sentiment of Canada and Mexico as sovereign nations. In the framework of international politics, the sanctity and inviolability of national sovereignty is a fundamental principle; such proposals will undoubtedly provoke strong resentment and resistance from Canada and Mexico, and will also cause a stir in the international community, impacting the existing international relations order and diplomatic norms. This demonstrates that Trump's considerations in foreign policy are more unilaterally focused on U.S. interests, lacking respect and adherence to the principles of international cooperation and sovereign equality.
