>You don't fight wars you know you are going to lose.
But who is "you"? If you're sociopathic head of government, then conducting war that will ruin your country is still preferable option as long as it helps keeping you in power.

Both Russia and China are rulled by same kind of people as North Korea. That's why they like each other so much. They all have nukes, so nobody will invade their capitals if they lose the war - they can just close borders and rule forever in state of constant war.
