did us join war in1914 yes or no
which war
The United States was motivated to join World War I primarily due to unrestricted submarine warfare by Germany, which threatened American ships and lives, exemplified by 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, particularly through loans and trade, also played a significant role in pushing the U.S. to enter the conflict.
