After the communists gained control of China in 1949,

c.most Americans recognized that their triumph resulted from a long internal conflict within that country.

Explanation:

Rise of communism in China was not something that the US could have prevented in any capacity due to the long drawn out conflict in the nation that had resulted in the communist take over by its own means

As much as the US would have wanted it to be otherwise this was to be the case without any doubts in the matter.

So, eventually the government had had to accept that fate and had to work with it as they could not boycott this china by any means.

china unilaterally claims the entire south china sea as sovereign territory, then builds artificial islands to bolster its claim. it suddenly activates an air defense identification zone over the east china sea, and threatens to down any aircraft that does not report its position. it builds roads into indian territory, then redraws the maps to show that it is actually chinese territory. the people's republic under president xi jinping is quickly becoming the bully of asia.
