This isn’t accurate. The thing that’s going to possibly be depleted is “Arrow 3” - the first line of aerial defense (excluding operations that target the launchers within Iran). They still have plenty of Arrow 2 and David’s’ slingshot missiles.
This is all very unfortunate. However - once the world realizes that deepfakes can be generated virtually for free and for anyone, no one will trust them. We might even be better off with them rather than without as no one could tell if a genuinely leaked photo of yours is real. The same has happened with phone records as evidence in court (in some countries)
