Step-by-step explanation:
The Zimmermann Telegram had a significant impact on the relations between Mexico and the United States during World War I. It did not destroy strained tensions between the two countries, but rather caused an escalation of tensions. The telegraph, sent by Germany to Mexico in 1917, proposed a military alliance against the United States. This action caused outrage among the American public and ultimately led to the United States entering the war.
The Zimmermann Telegram further contributed to the war efforts by portraying Germany as the enemy, encouraging young men and women to join the war. It heightened the sense of urgency and patriotism by revealing Germany's aggressive plans. However, it did not primarily scare the people living in Texas, New Mexico, and Arizona as they feared being removed. The impact of the Zimmermann Telegram was both political and propagandistic.
