Populism doesn't quite capture it because it's not necessarily about the rise and fall of specific parties or individuals or even a kind of neo-populism that can be defined by academics. It is more about a general reaction to the exposure and failures of the 9/11 wars and the repercussions of the 2008 financial crisis: ultimately, the destruction of the orthodoxies of liberalism and free market economics combined with the destruction of the concept of objectivity and faith in a shared concept of truth on a popular, instinctive level.
Conspiracy theories, "alternative facts", accessible fringe media supplanting mainstream channels, the scrambling of established political categories, etc.: all of these things are visible and gestating in the 2010s, but they are not quite of it.
