The ultimate human game-theory game is kill-or-be-killed.
Historically, all empires, states, and political groups have proved this fact. Presently, covid biowarfare is proving this fact.
What can I do as an individual? Nothing to change the above. But many things to change yourself.
The briefest way to state what to do is Buddhist practice.
The First Noble Truth of suffering has always been true and is confirmed in our time.
The Second Noble Truth of the cause of suffering has always been true and is confirmed in out time.
The Third Noble Truth of the cessation of suffering largely depends on individual behavior, as defined by Buddhist practice. The human realm is trapped in the ultimate game-theory game, but the individual is not because the individual can let go of the causes of suffering and rise spiritually.
The Fourth Noble Truth of the way to end suffering is the Noble Eightfold Path. This way also largely depends on induvial behavior, diligence, concentration, and activity.
Buddhism is not nihilism, theism, or atheism. It is a stark recognition of the reality of the human realm. By our own efforts we can recognize our position in this realm and grow spiritually through Buddhist practice.
