Answer:
President Washington warned against political parties and issued a Proclamation of Neutrality.
Political parties developed early, with Hamilton leading the Federalists and Jefferson leading the Democratic-Republicans. Washington warned against them, believing they would divide the nation. We did not listen to this advice, shown by the Democratic and Republican parties today.
The Proclamation of Neutrality was Washington stating that the US should not interfere in the affairs of other nations. The US was a young nation at that time, and Washington did not want it interfering with more powerful nations. We did not listen to this advice, as, for example, James Monroe led the US to interfere in the affairs of Latin American nations.
The results of our nation's response are to divide the nation based on political party, but also to assert the US's dominance as a world power.
