Then why was he killed? Without knowing who gave the orders, it’s possible to understand that the current political environment allowed for this to happen. Over the past year, in the wake of the annexation of Crimea and the war in eastern Ukraine, Russia has seen the rise of a new, much coarser and more doctrinaire political language. During the first decade of Putin’s rule, the Kremlin depicted its opponents as freaks or idiots, but now they are portrayed as outright enemies of their country. In a triumphant address to parliament last March, as Russia was formalizing its takeover of Crimea, Putin warned of “a fifth column,” a “disparate bunch of national traitors” determined to sow discord inside the country. Its members were obvious, if at first unmentioned: people like Navalny, an anti-corruption activist who had become the most popular leader in the country’s fractured opposition; Aleksei Venediktov, the editor-in-chief of Echo of Moscow, a long-beleaguered radio station that is one of the last homes for critical and liberal voices; and of course Nemtsov, a recognizable facefrom all his years in politics, and a favorite opponent of pro-Kremlin activists and propagandists.
