briefly explain, what happened that pulled America into the war, what Wilson says the goals of our fighting would be, and why Wilson believes the fight is so important. (Wilson's speech to congress)

On April 2, 1917 President Woodrow Wilson addressed a joint session of Congress to request a declaration of war against Germany. When the Germans resumed sinking our ships without warning, the United States declared war on Germany and fought on the side of the Allies.  

It was a somewhat surprising turn of events. Earlier in his presidency, Wilson coined the phrase “America First,” and his supporters proudly waved banners at the 1916 Democratic National Convention extolling, “He Kept Us Out of War.” Now Wilson was explaining that “Neutrality is no longer feasible or desirable where the peace of the world is involved.”
