The Zimmermann Telegram and the sinking of American ships and the British-owned Lusitania (with 128 American lives perished) urged America to mobilize for war against the Central powers. The Zimmermann Telegram was sent by German Foreign Minister Arthur Zimmermann to Mexican Government to suggest that they should declare a war against the US to get back the territories they have lost in the Mexican-American War. However, the British intercepted the telegram and immediately informed the US Government.
The Cold War started after the tension the Soviet Union started it wanting to become a world power. They started making more weapons and advances than the U.S. This caused us to want to also expand so that we could stop communism from spreading and protect capitalism. The Soviet Union developed nuclear weapons greater than ours and positioned them off of Cuba at the U.S. These lead to us making nuclear weapons. Eventually we called for an agreement to reduce the amount of weapons we had so that we could peacefully coexist with the Soviet Union.
The laws <u>backfired</u> because the German workers unified in support of socialism.
I think it was Woodrow Wilson due to his term time and him being the father of the Progressive movement.
