Totally, our leaders fucking suck. But also I would like to argue it is a really great thing our leaders are (at least most of them) just regular people like you and me. And I don't know about you, but I suck from time to time too. Also fuck up everyone once in a while, make mistakes and am sometimes misinformed as well. I think we should collectively work on improving the system but also give the part of the idiots that do mean well some lenience. I think calling all politicians idiots, snakes and blood drinking lizards can be a slippery slope that can have very serious consequences in the long run.
But I agree it's totally worthless barely anybody is speaking up against Netanyahu in a meaningful way, even after so many recorded war crimes.
We have a similar system in the Netherlands but a meaningful difference is that you don't only need a 2/3 majority but also a 'confirming' vote by the next coalition. This might not do much in a case like Hungary or Turkey where the next ruler is similar as the previous but there having to be a public vote in between can potentially greatly shift the powers and end the majority.
