The April 1 editorial “Mr. Putin’s deal with the devil” revealed the thinking that an enemy’s foe and friend will be your friend and foe, respectively. Fair enough, but you may end up dealing with ugly customers — were four Britons not executed in Chechnya by anti-Russian separatists in 1998, the U.S. ambassador to Libya by anti-Gaddafi insurgents and numerous Western journalists in Syria by anti-Assad terrorists?

So if Ramzan Kadyrov, the Chechen ruler, is a devil or a glorified gangster, he is at least a wise one. Like a general who realizes he’s outnumbered might say to his troops: Brothers, we lost the war. Yes, things were easier for the West with Mr. Putin’s predecessors, but he prefers to dance to his own tune — at home and abroad.
