The United States was affected by foreign policy issues with Isolationism. An example of Isolationism is the Treay of Versailles. This is an example becuase the Senator denied the approval of this foreign policy. The U.S wants nothing to do with foreign affairs anymore after World War 1. Also President Wilson Fourteen Points document was an example od Isolationism. Senator Henry Cabot Lodge speech discussed his preference for Isolationism in order to keep the U.S in ordered liberty/peace. and the largest freedom country in the world. This speech essentially caused the rejection of the Treaty of Versailles.
The United States was also affected by social/politcal problems with the Red Scare. The Red Scare was mainly about the (fear) rise of communism in the U.S and Worldwide. The Red Bolsheviks in Russia won the civil war and adapted a communist government in the Soviet Union in 1917. Commuism then expanded in russia following with violent strikes in 1919 ,which lead to the Palmer Raids. As communism spread across the board and expanded in the United States, Attorney General A Mitchell Palmer lead unauthorized raids on businesses and homes that were suspected of communism. The search results in finding no eveidence of communism but instead resulted in getting over 6,000 immigrants arrested and deported.

This was the time of the Great Migration at which thousands of African Americans migrated from the south to the north. Also this was a time of economic struggles related to high unemployment which was a result of great migration. Although this may not some like such a racial problem but it actially created alot of racial tension across the north. Several groups of whites would attack blacks in several cities at a time. In Chicago, 38 were killed and 1,000 were wounded, in Washington D.C 15 were killed and 100 were wounded, and In Nebraska the lynching on Will Brown took place. Innocent negros were being randomly beat by soldiers, sailors and even marines. The bad thing about this all is the The President knew about this racial problem and had the authority to stop it and didn't
