CAIRO — King Abdullah II of Jordan leads one of the smallest, poorest and most vulnerable Arab nations. But that does not stop him from looking down on many of those around him, including the leaders of Egypt, Turkey and Syria, as well as members of his own royal family, his secret police, his traditional tribal political base, his Islamist opponents and even United States diplomats.

President Mohamed Morsi of Egypt has “no depth,” King Abdullah said in an interview with the American journalist Jeffrey Goldberg, to be published this week in The Atlantic magazine. Prime Minister Recep Tayyip Erdogan of Turkey is an authoritarian who views democracy as a “bus ride,” as in, “Once I get to my stop, I am getting off,” the king said.

And he said President Bashar al-Assad of Syria is so provincial that at a social dinner he once asked the monarchs of Jordan and Morocco to explain jet lag. “He never heard of jet lag,” King Abdullah said, according to an advance copy of the article.

The king’s conversations with Mr. Goldberg, an influential writer on the Middle East and an acquaintance of more than a decade, offer a rare view of the contradictory mind-set of Washington’s closest ally in the Arab world as he struggles to master the upheaval of the Arab Spring revolts. Seldom has an Arab autocrat spoken so candidly in public.
