What caused the us to get involved in World War 1?

Answer 1

The United States entered World War I primarily due to unrestricted submarine warfare by Germany, which led to American ships being attacked and American lives being lost, notably the sinking of the Lusitania in 1915. Additionally, the interception of the Zimmermann Telegram in 1917, in which Germany proposed a military alliance with Mexico against the U.S., further inflamed public opinion. Economic ties to the Allies and a desire to promote democracy also motivated U.S. involvement. Ultimately, these factors culminated in President Woodrow Wilson asking Congress to declare war on Germany in April 1917.
