If Iran comes out of this shit show and survive, I will hope that Iran go crazy on buying and the locals who aided Israel, least I expect Iran to order J-10's 2 full sqs with either SD-10's or Pl-15E's, order HQ-9B's from China within few months as China is only country that provide fighter jets, SAM in short time. Russians did nothing for Iran and provided nothing including the Su35's, I mean they did lets say within few months/Weeks than sure, anything to harass the IDF fighters over Tehran, but I think Iran will be building more new Missile bases much deeper this time including ones to host enriched Uranium.
I think Iran can take a step back and assure that they will no pursue Nuclear weapons but build a damn good conventional military, knowledge is there in Iran infrastructure can be build again, And Honestly I would say If Iran get the nukes at some point it will force KSA to get their own weapons which will than have 3 major Muslim countries with nukes, it balances the power in the region, KSA is like Iran full of empty land and can build some deep underground bases to accommodate, If countries have nukes as Deterrence than it lower the risk of major wars as the world find some sort of peaceful way to resolve issues, and Pakistan/India is prime example of it, both countries have nukes and despite launching Missiles/Air strikes at each other both hesitate to go into full scale war which escalate to a point of no return, and America came in to offer a cease-fire which both India/Pakistan accept, and its holding so far pretty good.
