The U.S. joins the World War 1
There were many factors that caused the U.S. to finally join the war across the Atlantic Ocean. The first factor that caused this was: the Sinking of the Lusitania in 1915 that killed 128 Americans and about 1,100 people in total. Also, in 1917, Subs continued to attack the U.S., causing America and President Wilson to become more aggravated. The last blow was when Germany sent a telegram that was intercepted by the U.S. It was a telegram to Mexico, trying to persuade them to attack the U.S. so that they could earn their land back that they had lost a long time ago a in a war. America and the President became furious. So, on April 6, 1917, the U.S. joined its Allied friends in the WW1! Although many Americans didn't favor the joining in that war, U.S. did eventually end up joining that war.
