China is our problem. China dealing with other Chinese is not worth one drop of American blood. After 75 years of bleeding all over the world for countries that don’t give a damn about America, haven’t you had enough?
Your sentiments are not altogether wrong. Involving ourselves in many foreign intrigues has frequently been a fiasco. With respect to China, the reason they went Communist was in great part due to our failure to support Chiang Kai-shek and too many at State (a den of Communist seditionists even then) directing measures to aid Mao (they also helped Castro, too).
Had Truman allowed MacArthur to conduct the Korean War to the fullest and liberated the peninsula entirely and pressed onward to defeat Mao, we would not have had the problems we had in that part of the world for all the decades since.
Indeed, with a Nationalist China, they’d have crushed the Communist uprisings throughout Asia and we might never need to have gotten involved (Vietnam, the premier example).
Sending troops now isn’t going to work, of course, but surely there are covert means to assist the pro-freedom revolutionaries that we can utilize. Also working to destabilize Red China’s economy is another method, too.
