The United States transitioned fom isolationism to interventionism in the years before World War II. One of the main events that led to this change was the decision to join World War I, which came after the sinking of the RMS Lusitania by Germany. After this decision to join the war, the United States could no longer be considered an isolated country.
American involvement in international affairs only continued to grow in later years. Although America had promised neutrality during the 1920s and 1930s, as a result of the trauma of the war, it decided to get involved in World War II when the situation in Europe had turned particularly dire. This involvement was also motivated by the attack on Pearl Harbor.
Finally, we can examine what the First Neutrality Act, the Cash and Carry Act and the Lend-Lease Act say. The First Neutrality Act was a law that prevented the United States from becoming embroiled in a foreign war. The document clarified American neutrality. The Cash and Carry was a policy that allowed European powers to purchase arms from the United States in cash, as long as they assumed all risks for transportation using their own ships. Finally, the Lend-Lease Act was a program under which the United States sold Allied Countries food, oil and other types of material for free, with some hardware having to be returned after the war.
