When information is a weapon, everyone is at war. We live in a world of influence operations run amok, a world of dark ads, psy-ops, hacks, bots, soft facts, ISIS, Putin, trolls, Trump. We’ve lost not only our sense of peace and democracy – but our sense of what those words even mean.

His research takes him back to Russia – but the answers he finds there are surprising.
