This is a backward way of coming to terms with conflict. In the modern world war is increasingly an outmoded way of handling conflicts. The number of wars, casualties in wars, and so on are a tiny fraction of what they have been historically. The idea that war is the basis of peace is held strongly by those who study wars, but a thorough analysis puts and social inequality and disasters such as famines as being both the current drivers of war and in many cases avoidable. At this time trade wars and competitions like the space race have a bigger effect on society than open conflict.

Don't go too far down that road because you can never be sure when a smart (but insane) person will get enough dissatisfied people and go to war. Thus everyone needs to know enough about war so that society as a whole can deal with war if it comes.

How much is left as an open question.
