A great deal of conditioning is needed to prepare most people to take part in war, and a great deal of mental suffering is common among those who have taken part. In contrast, not a single person is known to have suffered deep moral regret or post-traumatic stress disorder from war deprivation.
War is not a permanent part of our culture:
Any feature of a society that necessitates war can be changed and is not itself inevitable. The military-industrial complex is not an eternal and invincible force. Environmental destructiveness and economic structures based on greed are not immutable.
War is not created by crises beyond our control:
War in human history up to this point has not correlated with population density or resource scarcity. The idea that climate change and resulting catastrophes will inevitably generate wars could be a self-fulfilling prophecy. It is not a prediction based on facts.
Ending war Is possible:
Human societies have been known to abolish institutions that were widely considered permanent. These have included human sacrifice, blood feuds, duelling, slavery, the death penalty, and many others.
Ending all war is an idea that has found great acceptance in various times and places. It was more popular in the United States, for example, in the 1920s and 1930s. In recent decades, the notion has been propogated that war is permanent. That notion is new, radical, and without basis in fact.
