The problem with that approach is that Israeli law in 2023 (before 10/7) was changed to make impeachment of a Prime Minister practically impossible - likely to keep Netanyahu in office - as it requires a super-majority vote in the Knesset and for a conviction it needs to be final after all appeals.
Clearly undemocratic in spirit if not substance. We now face authoritarian in both the US & Israel. My maternal grandfather was Jewish and a staunch advocate for Israel as a democracy. I wonder how he would view today's events.
No doubt there was a colossal intelligence failure, deployment of IDF to the West Bank under Ben Gvir and Smotrich, failure to listen to the female observer and their observations - and of course Netanyahu's failure to call for a National Commission of Inquiry that would expose all the failings.
