Wars are how a nation chooses how people die during peace time.
2-6 million - Government and tax death toll
1.25 million - Road traffic accidents
100-400 thousand - Wars
65 million All cause deaths annually and globally
So wars are what all nations use to decide how the winning nation chooses how people live and die during peace time.
The reason War gets so much publicity is because people are tribal and obedient to the tribe above all else. That is all. So we care far more about tribal obedience than we do about more important things.
In the meantime, millions die in far far far larger numbers than war. This is the outcome of the tribal obedience which all people live by.
We care more about our tribal narrative and ensuring everyone obeys it, than we do about the major causes of death.
