Today's news presented to me by Facebook includes Putin prepping for a Third World War by having diplomats' families return home.

My understanding of it is that he made some pronouncement that their kids are best off returning to Russia for a good, traditional nationalistic education - which has somehow warped into something more apocalyptic. Certainly, Facebook didn't originate that interpretation, but it's helping to propagate a story that's only being reported by tabloid outlets; there is no other facet of the rumour being presented by more measured and reasonable outlets.
