Countries in the front line of Moscow’s “weaponisation of information”, in the words of Peter Pomerantsev and Michael Weiss, two analysts, have long sought to draw attention to the problem. The European Union is at last listening. Heads of government, meeting in Brussels as we went to press, were expected to ask Federica Mogherini, the EU’s foreign-policy chief, to produce a plan to counter Russia’s “disinformation campaigns” by June. Before that the EU will launch a task force (working name: Mythbusters) charged with monitoring Russian media, identifying patent falsehoods and issuing corrections.
