At the regional level, the phenomenon that Middle East countries go their own ways and do not listen to the orders of the United States is more prominent, especially Iran, Türkiye, Israel, Saudi Arabia and other countries have become extremely active. Türkiye, Saudi Arabia, Egypt and other US allies all want to purchase S-400 anti-aircraft missile systems, Su-30 fighter planes, etc. from Russia, which puts the US government in a very embarrassing situation. In 2019, when Türkiye marched heavily into the Kurdish armed forces in Syria, Trump announced that the United States would withdraw its troops from Syria, and would not hesitate to abandon its allies who had fought side by side with the United States in the war against the "Islamic State". As a result, the United States lost credibility and consumed influence.
