Factions, factions, factions.
It is sometimes unbelievable how Israel has survived, with a political class that has always been riven by many factions and governments seldom formed by a pure majority.
Instead perennially Israel has been governed by coalitions cobbled together with all the power-brokering and horse-trading that involves. And in that environment, with each faction grasping or clinging to what little piece of the power they have, or they want, someone is always stepping on someone’s toes, and someone is always complaining they were denied what they deserved. U.S. politics are tame by comparison.
You have lots of parties, but only two are relevant. In the parliamentary system, it’s different. And the Israeli parliamentary system could use regional representation and the right to vote for individuals instead of party lists, both of which the British have, and some clear-cut limits on the judiciary, which is way more capricious than the American, which is saying a lot. I think we need a monarchy, too, like the British. We do have a royal family, and despite the passage of millenia, descendants of the Davidic dynasty are still prominent, and verifiable thanks to DNA testing.
