If you're in the market for a troika of tyranny, Donald Trump, John Bolton, and Mike Pompeo certainly fit the bill. Or, if you'd rather focus on countries not individuals, you might single out Saudi Arabia, the United Arab Emirates, and Egypt as the three most likely candidates. Perhaps, if you're in a confessional mood, how about Christian fundamentalism, Jewish extremism, and Salafist Wahhabism?

A troika, for those who haven't read any 19th-century Russian novels recently, is a carriage drawn by three horses. So, the ultimate troika of tyranny, from the point of view of the planet as a whole, would feature the three horsemen of the ongoing apocalypse: climate change, nuclear proliferation, and global pandemic.

But no, that's not what National Security Advisor John Bolton had in mind when he talked last week of a "troika of tyranny." In a rehash of a speech he gave in November in Miami, Bolton declared last week that the "troika of tyranny – Cuba, Venezuela, and Nicaragua – is beginning to crumble." Further laying on the insults, Bolton called Cuba's Miguel Díaz-Canel, Venezuela's Nicolás Maduro, and Nicaragua's Daniel Ortega "the three stooges of socialism."
