(A) Germany’s War secrets promised to the Mexican government after the United States entered the war
(B) ** Germany’s proposal that upon an alliance with Mexico, it would ensure the return of Mexican land lost to the United States
EXPLANATIONS BELOW
Concept note-1: -The note revealed a plan to renew unrestricted submarine warfare and to form an alliance with Mexico and Japan if the United States declared war on Germany. The message was intercepted by the British and passed on to the United States; its publication caused outrage and contributed to the U.S. entry into World War I.
Concept note-2: -In the message, Zimmermann instructed the German diplomats to approach the Mexican government, if United States entered the war in Europe, to offer an alliance between Germany and Mexico.
Concept note-3: -Zimmermann’s alliance proposal did reach the desk of Mexican President Carranza, but it was officially rejected once a military commission determined that there would be no benefit in accepting it.
Concept note-4: -The Zimmermann Telegram affected American neutrality in World War I by ending it. After Germany confirmed the contents of the Zimmermann Telegram in March 1917, public outcry in the United States led President Wilson to ask Congress for a declaration of war against Germany.
