二战结束后，美国凭借着强大的经济和军事实力，迅速成为全球的超级大国，领先其他国家几条街。然而，近年来中国经济发展势头迅猛，按购买力平价计 算，早已超过美国。这一变化让美国感到不安，觉得自己原本的霸主地位开始动摇。 自2018年起，美国便开始发动贸易战，针对中国商品加征高额关税，声称此举是为了保护本土产业，减少贸易逆差。当时美国政府充满信心，认为通过加关 税可以迫使中国做出让步，甚至将一些制造业带回美国。然而，事情的发展并不像他们预期的那样顺利。关税政策实施后，美国消费者成了最大的受害者， 购买中国商品的成本大幅增加。研究数据显示，每年美国因关税多支出几百亿美元，平均每个家庭的开销增加了1000多美元。与此同时，许多美国企业也受 到影响，供应链被打乱，成本飙升，迫使公司提高产品价格，最终将成本转嫁给了消费者。 在地缘政治方面，美国也不断通过军事和外交手段对中国进行围堵。自2019年起，美国加大对台湾的军售力度，向台湾出售F-16战机和导弹，试图加强在印 太地区的战略布局。然而，中国并未坐视不理，反而提升了自己的海军力量，辽宁舰、山东舰等航母常态化巡航，形成了与美国航母舰队的对抗局面。南海 的岛礁建设也被中国稳固 ...
