War today in the future

War today, as prognosticated by T. Baron Russell in 1906 in his book A Hundred Years Hence:

we may take it as quite certain that war as an institution will be as obsolete as gladiators in the year 2000. Even if the increasing amenity of the human race did not abolish war, two other things would be certain to do so. One is the enormous development, already clearly in sight, of the means of destruction : the other the revolt of the peoples against the stupendous cost, not merely or chiefly in time of war, but also in time of peace, of modern armaments. The rising tide of educated democracy must inevitably banish war.
