Why did the US fail to change China once for all?

Q: Why did the US fail to change China once for all?

A:

What kind of change are you talking about? Change China to what?

Do you mean genocide? Like in the 18th century, killing all the Indigenous people, wiping out their civilizations, and occupying their land of America and Oceania? That’s an example of “once for all”.

Or do you mean colonizing China? Like in the 19th century, Europeans colonized the whole world, except China. We know that’s not “once for all”.  Virtually all countries became independent after WWII.

Maybe you mean to have China adopt Western democracy. NATO was successful in having the USSR adopt Western democracy and the market economy. But is it “once for all”? If it is “once for all”, we should have the Ukraine War.

If the US wants to make regime change, it is in the American interest, not for the people of that country, and not for democracy. The US attempted multiple times to change China by supporting dictators. In the Chinese Civil War from 1946–1949, the US supported dictator Chiang Kai-shek. In the Korean War, the US supported dictator Syngman Rhee. In the Vietnam War, the US supported dictator Di?m. All three wars were aimed at changing China, and in all the wars, the US supported dictators.

The US failed in all three wars. In all three wars, Mao defeated the US. The US failed to change China because of Mao.
