When the war is fought over literal nuclear weapons, you should not be so tongue-in-cheek about calling a war nuclear.

Iran has no nuclear weapons. The administration simply wishes to prevent Israel from facing opponents that also have a nuclear deterrent (Israel has nuclear landmines, briefcases, missiles, and neutron bombs according to Sy Hersh). A deterrent would radically curb Israeli aggression and maybe even end the genocide in Gaza. There is little risk Iran would use a nuclear weapon. This is pure western aggression.
