Would you live in Israel knowing what you know? Would you move there? Would you stay if you had ever ability to leave? How would you feel about someone who did?
If I were a jew I would not want to live their. I don't want to live in an apartheid state and would not want to live under the extreme right wing government. Nor would I want to live in a place that is so prone to beeing the target of a terrorist attack. So moving there would be our of the question.
As for your other questions: There are Israelis who belive on a 2 state solution and are against the government. There are Israelis who have family who love there they do not want to leave back. People have been living in Israel for 75 years. That's two generations growing up there. It's not that easy to just go away. Nobody thinks that US citizens should leave their county, and they got it by committing a genozode and settling land that didn't belong to them. Just 100 years earlier as Israel. So if you realy hold the stance that people should leave Israel you better apply that same logic to the US.
No, not true. They are saying that this time they knew to watch close, so the Democrats couldn't pull of the same fraud as 2020. They are indeed stating that it is "supisious" that 13 Million Democratic voices where nowhere to be seen this time around, taking that as proof they were right all along.
That's how this works. You take reality and then make it mean what you want it to mean. So that's their take in regards to voter fraud.
