I agree.To much talk about simple matter, prompt remedy for lack of numbers and capabilities are russians and chinese, first one with licenced production other one with fast delivery, everything else is on long stick and draining water from stone.
Both will not happen due their position towards Iran considering it as junior partner at best and their own geopolitical concerns.
Iran is really at the crossroads as far as combat a/c are concerned.
Fastest way will be to attempt to acquire surplus airframes - MiG-29's of course - and have these upgraded to -SMT standard. Hopefully in so doing also giving a nod to Iran's own aerospace industry, especially pertaining to electronics, EC/CM and radar. Weapons?
Regarding Russia and China, if Russia gets offered a face-saving deal in Ukraine that excludes Iran -Iran will be dropped like a hot coal.
China: The only chance, and this is a long one at that, is to attempt to acquire 'green' FC-1 Xiaolong's (Chinese JF-17's) from it. Green in the sense that it will be flying with the engine and other flight controls installed.
Iran will have to fill in the blanks, such a the radar, nav/coms, EC/CM's, BVR and WVR AAM's.
License production once and when there are sufficient rubber on the tarmac.
