There was a coalition of 4 parties and he was part of the more moderate one. The 3 (technically 2 since the big extreme rightwing one already got out but still make the majority of parlement rightwing) other coalition parties stopped any attempt at doing anything against israel, so he just ragequit basically.

I really hope the next election is gonna fuck over all the rightwing parties but… Yeah… People are still as dumb as last election probably.
