I wouldn't put much stock in the assertions of this article -- they seem steeped in anti-Russian brainworms and cite no sources or specifics -- but this is the shit you stay up on if you're a "serious" Foreign Policy Expert. And the take it's running with today is "Russia is actually better at this than Ukraine now."
