If TR was President during WW1, what would happen? Now I dont care how he wins in 1912 and I dont want to look in the archives. Would the United States enter the war in 1914? Would TR enlarge the military? I plan to write a story with TR as President during WW1 and I need some answers. If there still is a WW1 witha ll the butterflies, what would it look like? Would the war end much quicker? Thanks.
