People always seem so resigned and certain in their beliefs that warfare and killing are inevitable and impossible to avoid. It always strikes me as almost irrational in a way, or perhaps it’s a sort of sunk cost fallacy wherein once you’ve committed to military conflict, it’s extremely difficult to go back on it as that would require admitting the already existing destruction and death that has accumulated was all for nothing. And so to protect themselves from such a truth, they continue the cycle of death and destruction knowingly or unknowingly acting to condemn their children to the same fate.
Thus the resignation of fate, giving up, and falling into an endless cycle of destruction with which the second paragraph consists of. What parts do you find vague?
