There is an area in Syria that is hotly contested. The Iranians have tried to move in Surface to Air installations and had them taken out. This area is used by the Israelis to inflight refuel to reach Iran. The Refuelers aren't stealth and would be suseptiple to the SAs. No, the F-35A does not have quite the range to go everywhere in Iran unrefueled. But it can go into Iran quite a ways without refueling in a Sensor and Camera mode. But in a war situation, it would be needed to be refueled as would all the other birds including the loaded down F-15s and 16s. So Israel keeps that one area in Syria SA clean. Both Iran and Syria cry to high heaven about it but Russia stays mute about it. Those flights have been complained about by Iran, itself. You can try and discount them but Iran says they happen and claims they are against International Law. Iran complaining about another country violating international law is a real hoot.
