Because they read the Zimmerman telegram and they got mad and entered the war and the second one was because the Lusitania got blown up and about 100 citizens died
What ultimately garner American public support for the First World War was the Zimmerman Telegraph, in which Germany supposedly asked Mexico to declare war on the US, and, in exchange, offered them the treaties which Mexico had ceded to the US with the Treaty of Guadalupe Hidalgo. The default answer regarding the Second World War is the attack on Pearl Harbour. In reality, the US government had been looking for a reason to enter into the war, and put pressure on the Axis forces to force their hand to do something which would garner the support of the American public for entry into the war. The Lend-Lease Programme and the oil embargo against Japan are the two primary means the government sought to achieve this. To remark on your first response to when America entered world war one, I would have guessed the Lusitania incident next to the Zimmerman Telegram intercepted by the British, but porportedly falsified to force the US into the war giving the Allies a surge of support.
The Great Depression of the 1930's ended when the U.S entered World War II. Entering war helps get out of an economic depression because it takes men out of the work force and puts them in the military, causing the rest of the U.S to enter the job market. Then they mass produce many products which causes the economy to boom.
