> You are advocating for no constraints (total war) on the stronger side. Taken literally, that means genocide of the losers. Really, that's what you want?

Taken literally, it means genocide of the losers is an option the winning side has. It always has been.

Note that Genghis Khan's explicit plan when he conquered China was to wipe out the Chinese to make room for Mongols. He wasn't stopped from doing that; there was no constraint to block him.

But he was persuaded not to.
