At some point the Israelis have to consider some constitutional reform to end this madness, don't they?
Whether it's increasing their seat thresholds or adding a seat bonus for the winning like in Greece, something has to be fixed if Israelis want an actual functioning government.
That would just reinforce the religious right which would in turn reinforce apartheid 2.0. The only way constitutional reform could work out without destroying liberal democracy in Israel is by adopting a secular, one-state solution. Either keep things as they are or give the Palestinians the vote.
In a reminder of a similar thing to the Brexit trilemma; there is a similar trilemma with Israel.
You can only have 2/3 out of the following:
>A single state in the area, from the red Sea to the Mediterranean
>A (primarily) Jewish state
>A democratic country
A 2 state solution, by definition, ditches 1.
Any sort of 1 state solution that gives a voice to the Palestinians in some way, ditches 2; no matter how loose the final result is.
Unilateral annexation of the West Bank means ditching 3. (or of Gaza but I doubt Israel would ever annex that)
My pick is to ditch 1 as I am deeply skeptical of such ethnic confederacies. Belgium is a disaster already and it is the "best case scenario"; more likely the new Levant state would look more like Bosnia or neighbouring Lebanon than Belgium.
