Israel is a geopolitical crime-in-progress. No crime has a right to exist, no criminals in the commission of a crime have the right to self-defense. They have the right to surrender to a competent authority, have the "issue" adjudicated by a fair judicial authority, and if found guilty to be subject to a proportionate penalty, and after having served their time, permitted once again to participate in lawful society.
The greatest existential threat to Israel,... is Israel.
