Seriously, the situation with the Chinese is >i the same as it was with the Soviet Union. For one thing, we didn't trade with the Soviets the way we do with the Chinese, to the tune of billions of dollars a year. The Chinese may want Taiwan back but in the long run they're going to do what's in their own best interests and that means avoiding a messy war with their number one cash cow.
Huge grain deals kept the Soviets from starving. Selling wheat to the USSR was a mainstay of American agriculture through much of the Cold War years. They didn't produce anything worth buying though, so we didn't have the same trade profile as we have now with China.
