EXPLANATIONS BELOW
Concept note-1: -Once decoded, the telegram read: We intend to begin unrestricted submarine warfare on the first of February. We shall endeavor in spite of this to keep the United States neutral.
Concept note-2: -The State Department promptly sent a copy of the Zimmermann Telegram to President Wilson, who was shocked by the note’s content and the next day proposed to Congress that the U.S. should start arming its ships against possible German attacks.
Concept note-3: -In response, Wilson issued the Sussex Ultimatum, a decree that said the U.S. would break diplomatic relations with Germany if German U-boats continued to sink unarmed vessels. Again, Germany signaled that they would not sink passenger vessels without warning.
Concept note-4: -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.
