Whenever we read an account of the beginning of WWI it’s necessary for the historian to first lay out the landscape of interlocking defense treaties that turned Europe into a sort of Venn diagram of fantasy militarism. To me, it’s a reminder of the great Avalon Hill game Diplomacy which we played in my high school Military History Club (AKA: D&D club) – everyone secretly negotiating with everyone else against everyone else. For Europe, the results were grim, and I needn’t go into them.
