If I were to have to pick the figure in Vladimir Putin’s inner circle who scares me the most, it would have to be Nikolai Platonovich Patrushev, secretary of the Security Council and the closest thing there is in the Russian system to a national security adviser. Patrushev’s profile has grown steadily as both cause and symptom of the system’s drift towards nationalist imperialism, and he best channels the worst impulses within the id of Putin’s clique.
