WWI: The Plot That Boomeranged:
"Make war together, make peace together... reconquer the lost territory in Texas, New Mexico, and Arizona" -- this was German Foreign Secretary Arthur Zimmermann's brazen proposal to Mexico if the US entered the war. But British Naval Intelligence intercepted Zimmermann's message and handed it to the Americans. President Wilson was shocked, and an outraged American public clamored for retaliation -- in April 1917, the United States declared war on Germany. |
