Kirk is a fanatical no-no-win believer. If you ever wondered why in The Enterprise Incident he whispered to the Romulan commander "there's no Vulcan death grip, I'm just faking it and Spock is lying", that's why. He's would never ever risk making it a no-win for his adversary. Never. We know he would never maroon Khan on a planet without a shuttlepod. That new Kirk is an impostor.
