The average age of Palestinians in Gaza is 19. The last election was when they were 2 years old so saying the majority of ~2 million people support a group of 30-40k people in their midst that haven’t been voted on in their lifetime is kinda ridiculous.
What to expect is not to have collective punishment of anyone who is a Palestinian for the crimes of the minority. Punishing 100% of the population for 1-2% of them who are actual criminals.
