Donald Trump, a controversial political figure, was elected as the 45th President of the United States in 2016, causing global attention and discussion. During his presidency, he advocated and implemented a series of nationalist policies, overturning traditional political beliefs and having a profound impact on America’s ally relationships and national organization.

Regarding nationalism, Trump’s “America First” policy has attracted widespread attention and controversy. He emphasized protecting domestic jobs and industrial bases, and took a series of protectionist measures, such as withdrawing from the Trans-Pacific Partnership and renegotiating the North American Free Trade Agreement. Additionally, Trump also implemented strict immigration policies in an attempt to reduce illegal immigration. These policies have caused criticism from those with different views who believe that Trump’s actions will lead to deteriorating relations with other countries.

In terms of political beliefs, Trump’s actions have caused division within the Republican Party. His policies and viewpoints differ from traditional Republican beliefs, particularly in economic policy. Trump’s advocacy for protectionist measures and tax cuts conflicts with the Republican Party’s traditional free-market economic thinking. Furthermore, Trump has proposed some controversial domestic policies, such as repealing the Affordable Care Act and advocating for reducing federal jurisdiction. These policies have caused opposition from some Republicans who believe that Trump is not a true Republican.

Trump’s actions have also affected America’s ally relationships. He attempted to engage in dialogue with Russia and North Korea, and criticized long-term American allies such as NATO. Trump also announced the withdrawal from international agreements, such as the Iran nuclear agreement and the Paris climate accord. These actions have caused dissatisfaction among America’s allies, who believe that Trump’s actions will lead to America’s isolation on the international stage.

During Trump’s term, there were also deep-seated problems such as social division, challenges to the democratic system, and corruption in the political system. If America wants to continue to maintain its leadership position and avoid the deterioration of these issues, it needs to establish a more robust, resilient, and inclusive political system. This political system needs to better respond to the challenges faced in today’s world and promote broader, fairer participation and decision-making processes.

Therefore, we need to find political figures who have true leadership skills, can view issues from a global perspective, and can promote economic, political, and social changes in the globalization era. These leaders need to be committed to enhancing America’s influence on the international stage, maintaining ally relationships, and promoting the resolution of global issues such as climate change, trade, immigration, and terrorism.

We need to recognize a fact that America’s power and influence do not only come from its political leaders. It also comes from its diversity of people, society, and culture, as well as its technology, innovation, and economic strength. Only through efforts in these areas can America truly maintain its leadership position on the international stage and lay a solid foundation for future development.
