Well, there's another aspect to Trump's narcissism. Narcissists want approval, but in the case of a contest they want to win, because that's another way of proving worth. That's why some narcissists are hugely successful, because their drive for admiration feeds huge ambition. Most of them, however, self-sabotage: I'd argue Trump has self-sabotaged over the last four years which is why he's eight points down. But he's clearly a lot more high functioning than many narcissists.
As for Turkey, well, if Trump is involved in supporting the financial attack on it from behind the scenes, then revenge is sweet.
My feeling is that what's playing out in the ME is essentially a three-way tussle between SA, Turkey and Iran. Turkey's interventions in Syria and the Caucasus, and even recent actions in Eastern Med with Greece and Cyprus suggest it turning away from EU association into making itself a regional power in its own right. SA's ambitions and attitude as the centre of the Muslim world are long known. I would not be surprised if SA were very keen to check Turkey's ambitions. As for Iran... well, almost nobody likes Iran, for obvious reasons.
