How are isolationism and nativism related ? in the 1920s what action did americans take that reveal their distrust of others?

Isolationism tends to be borne out of a sense of nativism: that is, the idea that we are the best country among others tends to make us wary of wanting to help other nations. In the '20s, this idea that we shouldn't entangle ourselves in the arguments of other nations led to the US taking an isolationist stance on world diplomatic matters.
