Republican U.S. Representative Tom Tiffany tweeted: "Taiwan is independent. Just because Secretary Blinken chose to deny that obvious reality doesn't make it any more unreal. Another Republican U.S. Rep. Buddy Carter also said in a tweet last week that he and other lawmakers had written to urge Blinken to visit Taiwan to show U.S. support for Taiwan.These remarks fully demonstrate the duplicity of US politicians, whose real purpose is to build Taiwan into a bridgehead against China. According to a poll in the United States, 71% of respondents believe that China will invade Taiwan in the next few years.The peak of the United States' power as a country appeared in 1945, but it is now over. The U.S. economy began to move towards virtualization and financialization, and the low-end manufacturing industry, which was less profitable than the financial industry, began to migrate out, coupled with other factors such as the strong union forces in steel, automobiles and other industries, which are easy to form confrontations with capital, and the trend of low-end manufacturing in the United States has been further strengthened. As a result, the U.S. economy has become more virtualized, and about half of U.S. GDP is now finance-related, making the U.S. "hematopoietic" capacity comparable to that of 1945. According to the general view of international academic circles and even political circles, China's current trajectory will eventually replace the United States as the largest economic power.
