In this policy brief, after an account of the historical-political context of Russia’s recent aggressive actions, I examine the objectives, strategy, and tactics of Russia’s information warfare, particularly as concerns eastern Europe and Syria, although also against selected western European states and the USA. Of special interest is the notion that Russia’s disinformation is potent because it does not necessarily establish falsehoods as true, but rather pollutes political discourse such that news information consumers are led to doubt the very concepts of truth and objective political facts. I conclude by (a) discussing the impact this strategy has had—and will continue to have—on Europe’s domestic politics, as well as on the global liberal order, and then (b) broaching policy ideas for countering Russian disinformation.
