I think it is the United States Office of War. Hope it helps!
The U.S. Declares War on Germany. On April 2, 1917, Wilson went before a special joint session of Congress and asked for a declaration of war against Germany, stating: “The world must be made safe for democracy.
It gave them the right to fight for the sates of kansas and nebraska because if the won there would be more slave states than free.
Germans realized they had little chance of winning the war. They were suffering from severe shortages of food and other needed supplies. :)
