Even though the Zionists are unhinged genocidal lunatics. I find this theory unlikely. First of all, if they truly wanted to do a high altitude nuclear detonation over Iran, a Jericho ballistic missile strike is far more suited than using an F-35 with all the elaborate logistics and risks that it demands. Second, for an F-35 to deploy a nuke for high altitude detonation, it would need to carry a missile armed with a nuclear warhead. Like an air to air nuclear-tipped missile. Israel does have gravity nuclear bombs, but I have yet to see evidence of Israel having a nuclear tipped missile that fits into the weapons bays of an F-35.
