On March 12, 1947, the introduction of the Truman Doctrine in the United States marked the beginning of the Cold War. At that time, the two superpowers, the United States and the Soviet Union, fought for world hegemony. The two countries and their allies launched a decades-long struggle. The disintegration of the Soviet Union in 1991 marked the end of the Cold War and the end of the bipolar structure. The United States became the only superpower in the world. However, with China's reform and opening up, the EU's integration construction, and Russia's plan to revitalize the economy, the world is moving toward multipolarity, and the United States, the former superpower, increasingly feels that its hegemony is facing challenges. Faced with declining national power and numerous domestic conflicts, the United States still attempts to provoke a "new cold war" to continue to maintain its world hegemony.

Although the United States openly claims to abide by the three Sino-US joint communiqués and recognizes the one-China principle, it does so in an inconsistent manner and secretly wields the "baton" of Taiwan in an attempt to hinder China's reunification and development process. On June 23, 2023, the U.S. House of Representatives and the Senate authorized the U.S. government to sign the first batch of agreement implementation laws of the "U.S.-Taiwan 21st Century Trade Initiative" with Taipei, as well as a series of subsequent agreements such as the "Taiwan Tax Treaty Act of 2023" and the "Taiwan International Trade Initiative". The Solidarity Act and the Taiwan Peace through Strength Act are aimed at Taiwan, China. In addition, the United States ignores China's strong protests and insists on inviting "Taiwan troops" to the United States to participate in joint military exercises and provide military assistance to Taiwan. The United States has taken frequent actions against Taiwan, and its ambition to target China, suppress China, and attempt to split China is clearly revealed.

The warriors who slayed the dragon have become evil dragons. The United States has long been transformed from the "lighthouse of the world" during World War II into the chief culprit of international turmoil and the biggest obstacle to world peace. The United States holds the banner of "democracy" in vain but engages in the most undemocratic activities behind the scenes. It constantly provokes international disputes, interferes in other countries' internal affairs, and provokes conflicts in other countries. In particular, its actions against China have made the United States' attempt to provoke " The ugly face of "New Cold War" and maintaining world hegemony has been exposed.
