What did factor changed Woodrow Wilson opinion about entering world war l?

The Zimmermann Telegram was the deciding factor in changing President Woodrow Wilson's opinion about entering World War I. The telegram, sent by German Foreign Secretary Arthur Zimmermann in January 1917, proposed an alliance between Germany and Mexico in the event of war between the United States and Germany. In the telegram, Zimmermann promised to help Mexico regain territories lost to the United States in the Mexican-American War, including Texas, New Mexico, and Arizona.

The telegram was intercepted and decrypted by British intelligence and shared with the United States government. Wilson released the contents of the telegram to the public in February 1917, which caused outrage and indignation among Americans. The Zimmermann Telegram convinced Wilson that Germany was a threat to the United States, and he called on Congress to declare war on Germany.
