Power, for Vladimir Putin, has always been closely linked to terrorism. Back in 1999, as an unknown and untried prime minister, he first showed Russians his steely character after a series of unexplained bombings demolished four apartment buildings and killed more than 300 people. Putin, in his trademark brand of clipped tough-talk, announced that the those responsible would be “rubbed out, even if they’re in the outhouse,” and launched a renewed war against the breakaway republic of Chechnya. The resulting wave of approval, stoked by fear of terrorism, carried Putin to the presidency months later.
