Don't listen to those devils."

You can call me a devil if you wish, but to me this is a classic example of a half truth. If you are already inclined to believe it, then you'll see it as the truth. If you're not inclined to believe it, then you won't see it as the truth.

To give some examples of people who are less likely to see it as the truth, go and tell Yemenis and Iraqis and Syrians that life has never been better. I'd imagine you'd be seen as a little bit kooky.

Would you do that, would you tell people who are facing famine that life has never been better? I'd suggest you wouldn't, because deep down you know what you're saying is only half true.
