Question

What was revealed about Germany when the British intercepted the Zimmerman telegram?

Answer 1

Answer:

A. Germany planed to declare unrestricted submarine warfare and attack all ships, regardless of nationality.

Explanation:

The telegram was considered perhaps Britain's greatest intelligence coup of World War I and, coupled with American outrage over Germany's resumption of unrestricted submarine warfare, was the tipping point persuading the U.S. to join the war.
