Historically, there's never been any such thing. At best, relative stability is maintained by cripplingly expensive wars until the economy implodes and the wars are no longer affordable.

Ethically and practically, mutually beneficial relationships are vastly more productive and stable for everyone except the psychotic predator class who would rather cover themselves with scraps and baubles than allow a peace dividend to grow the world economy.

It's self-styled 'realists' who are the biggest brake on progress and innovation.

Not everyone wants to remain a stupid rat chasing other stupid rats for scraps around a barrel. Some of us have more interesting plans.
