We’re an hour past the exact centenary of the end of World War I. The Armistice was scheduled for 11 AM GMT on 11/11/1918. All the soldiers who actively participated in that miserable multi year slog through mud, barbed wire, and mustard gas are dead. The remaining veterans of the resulting Second World War, just a generation later, are all passing quickly. Would that we could only humbly recall, and not grossly imitate.
But, to my mind, the major powers of today have been setting a course for outright conflict for so long (given the pattern of scores and centuries, mass miseries, unsubtle pressures, and proxy wars) that the third such international war is to be expected in the next few years. It’ll be a mess, with no definite safe harbors—I hope I am only hereby making my first successful stab at science fiction!—but I’d much rather spend my middle and senior years in peace.
