There never was a Deep Throat. They made up some interviews based on hunches and waited for who reacted. At any rate it accomplished the goal of making sure Nixon could not respond when the North Vietnamese invaded the South. That was the real goal behind crippling Nixon. That and the fact he got his for prosecuting Hiss.
