Saudi Arabia and its crockery-breaking heir apparent, Crown Prince Mohammed bin Salman, are, once again, opening up claims of advancing a more progressive future for the kingdom to doubt.

Faced with criticism from Canada over the treatment of two prominent human rights activists, Saudi rulers on Monday did the kind of thing that backward, insecure despots often do — they lashed out and penalized their critics.

Riyadh expelled the Canadian ambassador and announced a freeze on all new business with Canada, which counts Saudi Arabia as its second-largest export market in the Middle East . The Saudis also said the kingdom would withdraw from Canada the approximately 12,000 Saudi students on government-funded scholarships and family members and transfer them to other countries.

It’s not unusual for countries to balk at external criticism. But this Saudi retribution is unnecessarily aggressive and clearly intended to intimidate critics into silence. It’s the kind of move that, in the past, would have immediately elicited a firm, unified opposition from the West. So far, there’s hardly been even a whimper of protest.
