The real problem is that “peace” usually defined as the lack of organized warfare is when people really start dying. Any random human of the 20th century was far more likely to die at the hand of their own “peace” time government than they were to die in a war.

All the megacides of the 20th Century except the Holocaust occurred in times of “peace.” Even the Holocaust occurred far behind the lines in militarily secure areas.

The absences of open warfare if good but unless it is followed by implementation of a humane government it is just a prelude to the real disaster.
