Think about his conduct in the Middle East. He sucks up to Saudis, Turks and Iran alike. There’s no Islamist project he isn’t fond of. “Walls? That’s not who we are.”
I think he would love to see Shia and Sunni united, preferably behind him.
I’d love to see his PET brain scans interpreted, so I wouldn’t have to keep guessing about the precise way in which he is twisted.
One wonders about those head scars of his.
Of course, his entire life is sealed up from prying eyes.
