> ... centrist governments ... shoulder any blame
I agree somewhat. However, the fault of mainstream politics is one of failure. The fault of extraterritorial actors is one of action.
I think that mainstream governments in the rounds haven't done enough for hoi polloi in the past few decades, but also that perceptions of what they could have fine may often be unrealistic. There are many prophets - some shallow thinkers might say "just read [ Das Kapital | Friedman ] and do that", but i don't agree that ideology delivers the benefits it promises.
It was a tall order to expect the past few decades of governing parties to satisfy the people enough that they don't turn to AfD shit.
Mainstream politicians' capital comes from votes, an expensive and limited resource. Extraterritorial actors do not have this constraint.
Where i end up is: yes, we should blame tired neoliberal parties for failing the people and driving then to charlatans. But that blame should be tempered by an understanding that government is a game that never leaves everybody satisfied. But extraterritorial actors? They are somewhere between philosophically vacant and hostile, and they are fucking with us just because they can. The blame is categorically greater.
