What is the name of the political philosophy embrace by several post-war u. s. presidents?

American philosophy is the action, corpus, and tradition of philosophers related with the United States. I think that in no country in the civilized world is less attention paid to philosophy than in the United States. it is no problem  to apprehend that almost all the inhabitants of the United States conduct their understanding in the same manner, and govern it by the same rules.

in the 1800s, chinese workers migrated to the united states, first to work in the gold mines, but also to take agricultural jobs, and factory work, especially in the garment industry. chinese immigrants were particularly instrumental in building railroads in the american west, and as chinese laborers grew successful in the united states, a number of them became entrepreneurs in their own right. as the numbers of chinese laborers increased, so did the strength of anti-chinese sentiment among other workers in the american economy. this finally resulted in legislation that aimed to limit future immigration of chinese workers to the united states, and threatened to sour diplomatic relations between the united states and china.
