> for the first time since the post-WWII order, they are threatened by a real regime change.

It's only new if you are blind to post-WWII history.

In the western world alone, there was no shortage of incredibly vicious fights with communist/socialist groups in in post-war Europe (Most prominently in Italy and Greece), to say nothing of the various domestic decolonisation movements (The British and French governments were scared shitless of them), secessionist movements in Quebec, Spain, that entire thing in North Ireland (the understatement of the century), the Civil Rights and universal suffrage movement in the US, collapse of prominent dictatorships in Portugal and Spain...

State-threatening social upheaval is nothing new, we just have a particularly shitty flavour of it right now, as fascism and fascist-adjacent movements are currently waxing.
