That is not quite true, though, about European electoral democracies, is it?
You need only look at places like Germany (far-right AfD is the 2nd strongest), France (LePen was almost president), Switzerland with their "people's party", Hungary (far right actually in power), Italy (look at Meloni), and - most recently - the Netherlands.
None of this is to excuse the likes of Ben Gvir and Smotrich - but Israel is far from being an exception re. this scary, scary rise of a populist right with, to put this diplomatically, ever so slightly fascistic tendencies.
What is even more scary - and, again, Israel has this, too, and is no exception here - is how the center-right seems to think that by pandering to some of their polemics, they may save themselves (it's not working, voters who approve of this kind of ideology prefer the original over the "ASDA own brand" variety).
Again, none of this excuses the far-right government of Israel even remotely - but we would be exceedingly naive to believe that "it could never happen here".
