Did we sell Israel any in flight fuel tankers? Probably not. It’s not like Iran’s not developing nukes.
Israeli F-35i has excellent range.
Israel purchased 4 KC46A fuel tankers from Boeing. Not sure if they have been delivered.
There’s Jericho missiles. For emergency purposes, plenty of Israeli planes could make one-way devastating weapons delivery anywhere in Iran. And submarines could deliver devastating blows as well.
Given strong Iranian opposition groups, just taking out some of the heads of the snakes could solve the problem without devastation. More than one way to skin a cat.
