Capitalism is all about profits regardless of how they come about. War is always the best mean to generate economic activities and profits, of course it’s only a good opportunity for those who do not have to go to war. The “invisible hand” doesn’t care and doesn’t count who and how many have to be killed and maimed and how much and how long human suffering will be.
In economics the lost and suffering are called “externalities”. In statist politics, they are called “sacrifice” .
