I think the military pacifists here may have missed Max Hasting's point. Yes, better to have no war, but the Great War that Britain couldn't prevent - we simply lacked the military might to do so - would have had disatrous concequences had we not stopped the man with the spiky hat and his troop of butchers.
As for the programme, I thought is was well researched and well argued. Cetainly spurred me on to learn more about that period of history.
