For a dramatic narrative of the war listen to Dan Carlin's Blueprint For Armageddon. It is, as of this publication, still in his current episodes and, consequently, free. Dan is an odd sort of Statist, but his historical accounts are first-rate and worth every minute of your time.
For a discussion that you probably did not hear in the public schools, try Tom Woods's April 5 interview with Hunt Tooley, "The U.S. Enters World War I: Wilson’s Folly Revisited, a Century Later."
