You say furiously, with your hands behing your back where nobody can
see them, "Why you need me to end the war for you!"
Your right hand reaches up and has a Colt .45 in it. You pull the
trigger on Hitler and run.
Congratulations! You just ended the war early! The Americans give you
the Medal of Honor and the British give you the Victoria Cross. Nice
job, soldier. Wait... are you a soldier? I think you are now. Ah,
nevermind.
Hitler asks, "What would you like to know?"
