Unlike Indian Armed forces, Things progress in practical manner for rest of the world. First develop primary requirements and operationalize it and then keeping improving/adding upon them. Recently Israeli Air-force has shown its capability which is pretty impressive and this is high time we should come out of LM rivals propaganda ( I did ) and have a wise and broad opinion.Not really.
As for now, F35 is only IOC. And every body knows that it's a political IOC.
Other countries are not fool which is buying F-35 for Billions of dollar because some of them are facing very existential threats from their nemesis so there is no such thing like "political IOC''. F-35 is operational, Israeli even used it for combat duty and they are very impressed with its performance.
