How might have WORLD WAR 1 turned out different if the delivery of the Zimmermann Note was susccessful and acted on?

If the Zimmermann Note had been successfully delivered and acted upon, it could have led to a stronger alliance between Germany and Mexico, potentially diverting U.S. military resources away from Europe to address a conflict on its southern border. This diversion might have delayed or weakened American involvement in World War I, giving the Central Powers a greater chance of achieving their objectives. Additionally, a Mexican-German alliance could have opened new fronts in the war, complicating the strategic landscape for the Allies. Overall, this scenario might have prolonged the war and altered the eventual outcomes for both Europe and North America.
