The decision to stay neutral impacted the United States economy. The United States was still enduring an economic depression during the 1930s, and the outbreak in Europe helped
the United States get through the depression. For example, other countries needed war supplies, so they looked to American manufacturers to produce the supplies. Although the United States were not getting involved in the war, they still wanted to help out their allies in Europe, so they decided to give lower tariffs to them to help get the United States out of their depression, as well being loyal to their allies. With the need of supplies high, there became a need of people to produce the weapons. Jobless people now had a chance to work in factories to produce these supplies, helping cut unemployment. Without the United States staying neutral, it's unclear if we would've gotten out of the depression. Roosevelt's decision of neutrality also affected the United States politically as well. Roosevelt wanted to keep a good relationship with all countries during the war, so the United States did not have to deal with any foreign issues. Congress passed the Good Neighbor Policy in 1934 to help keep good relations with everyone and to keep peace between the countries. Also, before the war Roosevelt freed the Philippines of control and removed themselves from Asia, in hopes that no one in the area would see them as a threat. Congress also passed the Neutrality Acts during the 1930s, so if President Roosevelt decided to declare war, certain restrictions would be carried out. While Adolf Hitler, German Dictator, was going crazy with imperialism in Europe, Roosevelt also encouraged him to stop and tried to keep the peace between the countries. Although Roosevelt did all he could to avoid involvement in World War 11, he failed in his peace negotiations.
The United States decision to remain neutral affected the people socially as well. After what the Americans saw in World War 1, most believed it would be best if the country remained neutral instead of entering the war. They believed that they should still help out their allies, but getting involved would just not be worth it. When the Japanese bombed the United States naval base Pearl Harbor in 1941, most people's opinions on war changed. Most people wanted revenge for the surprise attack, and they wanted to go to war. Even the most isolation supporting congressmen agreed it was time to go to war with Japan, and officially entering themselves into the mess that was World War 11.
In Conclusion, that is how the United States decision to remain neutral affected them socially, economically, and politically during World War 11
