Answer: Wilson cited Germany's violation of its pledge to suspend unrestricted submarine warfare in the North Atlantic and the Mediterranean, as well as its attempts to entice Mexico into an alliance against the United States, as his reasons for declaring war.
Explanation: When President Wilson spoke to Congress on 2 April, asking that they vote for a declaration of war, he argued that the United States had no selfish interests in joining the conflict but that American participation would make the world safer for democracy. On 6 April the declaration of war was passed by Congress.
