I viewed part of a CSPAN presentation on June 27, 2015 by Margaret MacMillan, based on her book The War that Ended Peace: The Road to 1914. (It was probably a rebroadcast.) The presentation seemed serious, well-informed, and judicious in trying to be fair and balanced to Woodrow Wilson. MacMillan is more sympathetic to Wilson than I am, but she made it quite clear that he enacted serious violations of free speech.
MacMillan’s book is:
