Bearing in mind he has no reason to apologize for "the memo as a whole", how should he approach this? He's already said many times he was not saying what people are claiming he has said. It hasn't worked. Should he release a version 2 of the memo with the benefit of maybe someone else to help him edit it? How would that be received by his critics or the press?

Is there really anything he can say or do that will redeem his public image after he's been slandered on a global stage based on a internal-only memo that someone leaked to the public likely with the intent of ruining his life?

There is a point at which there is really nothing you can say to make a situation better, and you are better off just not saying anything further on the matter.
