Remember that nice ironic bit early on in The Bridge On The River Kwai, where the Japanese Commandant flings down the copy of the Geneva Convention which Colonel Nicolson [Alec Guinness] has offered him, & Nicolson says, oh ever-so sarcastically and crushingly, something like "If you have no regard for the rules of civilised warfare, then I have nothing further to say to you!"

And ain't that him told, just...!
