Doesn’t matter. An Israeli minister in a government elected by the Israelis said it. That’s their true intention.
Obviously they will ridicule him, because who would support that? People only support normal indiscriminate bombings of innocent civilians, but nuking is just a bit much. Maybe if Palestinians lived a little farther away, then it would be viable.
You’re free to study the history of Zionism, and watch recent and current videos of many Israelis (incliding Israeli soldiers) saying that all the land belongs to them (Jordan, Lebanon, Egypt, Iraq).
Those aren’t a couple of people. Those are the beliefs of Zionists.
