One of Russian President Vladimir Putin’s predecessors, Vladimir Lenin, is supposed to have coined the aphorism that “there are decades where nothing happens, and there are weeks where decades happen”.
It may be apocryphal. But even if Lenin didn’t say it, Putin must surely be thinking it now. In the course of just a few days, the system that has governed international affairs since World War II has been stood on its head. And in Europe, heads are spinning and minds are reeling.
