Why did America enter WWII?
There are actually 5 main reasons for the US getting involved in the 2nd World War:
- Germans started sinking US merchant ships taking supplies to England.
- Japan's unreasonable demands on the United States (re- instating oil sales and dropping support of the Philippines and China)
- German submarines beginning to shoot at US war ships
- England and France are typically our allies so we were going to enter the war eventually anyway
- Japan's attack on Pearl Harbor was the real reason why we entered the War. However 3 days later Germany declared war on us, even though we were not looking for any reason to fight.
