Keegan also refers, earlier in the piece, to Churchill's commitments to "liberty" and "the rule of law." (To which I silently added an asterisk having to do with the Empire.) To give the flavor of the article more fully, I'll quote the concluding paragraph:
Churchill's sun, at the beginning of the third millennium, has risen and, if it should seem to shine fitfully at times and places, is nevertheless the light of the world. No other citizen of the last century of the second millennium, the worst in history, deserved better to be recognized as a hero to mankind.I do think Churchill was a great war leader and that the particular moment matched his particular skills as orator and, to quote David Jablonsky, "Victorian man of action." However, the statements that the 20th century was "the worst in history" and that Churchill is the twentieth-century figure most deserving of the title "hero to mankind" are debatable. (Note: not wrong, just debatable.)
ETA: I'm reminded of a post a while back at R.P. Wolff's blog in which he went through a list of (supposed) 'great men' of the 20th cent., denying they were great, until he got to Mandela, who was, in his estimation, great (and in my estimation too, I'd hasten to add).
