Will the West remain committed to the rules-based international order when it is no longer the one making the rules? That will be one of the most intriguing questions of the next two decades.

If there is one principle that has united electorates, policymakers, politicians and media across the West, it is that rules matter for just about everything else. Disrespect of common rules has long been met with intense anger and a forceful response.

Consider the United Kingdom, where Prime Minister Boris Johnson’s raw charisma enabled him to win and hold on to power, effectively redrawing the country’s political map in the process. Until recently, his public approval had withstood florid displays of incompetence, a rising pandemic death toll and an economic recession. But Johnson is now finally hemorrhaging support for one simple reason: He and his government went too far in disregarding the rules. The revelation that there was a Christmas party at 10 Downing Street (the prime minister’s residence) last year while the rest of the country was in lockdown has hurt Johnson’s reputation more than any of his other scandals or transgressions.
