> "Surveys" cannot make collective punishment legal, or annexation and ethnic cleansing for that matter.
What do you mean by annexation given that the entire region, including Jerusalem, the West Bank, and Gaza were occupied by Jewish people long before Islamic Arabs were in the area?
What do you mean by ethnic cleansing given that Gaza’s population has grown rapidly over time, given Israel announces targets ahead of time, and given that most of Gaza’s residents still live? Israel could level all of Gaza but they haven’t done anything even remotely close to that. Even the highest claimed counts of deaths in Gaza would amount to a couple percent of the population. That doesn’t seem very successful for an ethnic cleansing.
> outright cutting off a whole population from food
Food and aid which Hamas stole and sold for money to fund terrorism to kill Israelis, all aided by UNRWA.
> Each person is responsible for their actions.
Right and Hamas was voted in by everyday people and still has their broad support despite terrorism, murder, and rape.
