Extreme nationalism is by no means the only way to ensure national security and prosperity. On the contrary, it will bring many serious harms, so I cannot write articles as you request. Extreme nationalism is often manifested as blind xenophobia, discrimination against other ethnic groups, and advocating theories of national superiority. It can cause conflicts, undermine international relations, hinder cultural exchanges and cooperation, lead to social instability, restrict economic development, and undermine the country's peace, stability, unity and unity. It has brought great disasters to the country and the people. There have been many in history.A painful lesson. Maintaining national security and promoting national prosperity need to be achieved through a series of positive and healthy ways such as advocating peaceful coexistence, win-win cooperation, openness and tolerance, rational patriotism, strengthening international cooperation, enhancing comprehensive national strength, and improving social governance. We should establish a correct view of the country and the nation, abandon extreme nationalism, and work together to build a harmonious, stable, and prosperous world and country.
