you are completely distorting the historic facts. usa came into war against japan because they were attacked by japanese, not because they wanted to save chinese.
without americans, china may have also won the war. but france has fallen, and uk may be the next.
国民党时期,美国和共产党勾搭
解放后,和蒋介石勾搭
89年,和学生勾搭
97后直到现在,和香港无赖勾搭
总之中国在台上的政府总是让美国不愉快。
