The discovery of the Zimmermann Telegram played a role in the entrance of the United States into the war because it revealed Germany's intention to offer support to Mexico for plans to invade the U.S. This threat to national security greatly angered the American public and government, leading to President Woodrow Wilson's decision to declare war on Germany.
