There's an old apocryphal story about the Chinese and the Japanese duking it out in the prelude to WWII that applies here, but there's also a poem far closer:
> That though all lances split on you,
> All swords be heaved in vain,
> We have more lust again to lose
> Than you to win again.
> That though all lances split on you, > All swords be heaved in vain, > We have more lust again to lose > Than you to win again.

The side that is willing to loose one more time than the "winning" side is willing to win ... they win in the end.
