Maybe Pak has been a part and parcel of this stealth fighter project from the beginning! Only now that the Indians are over the board with Rafaels they're disclosing it in a candid manner. And, thanks to 02-26 to 02-28, RSS/Hindutva/BJP, Kashmir lockdown, IK's equating them to Nazis with facts etc. nobody would object to Pak's having as much potential deterrence as possible. No world power would want a "nuclear exchange", which would peril their way of life, comfort zones etc. Modi/RSS/Hindutva etc. have proved themselves to be hovering on the edge of the sanity with the physical proofs....
Even the Indian strategists are talking about "interoperability" b/w the Pak and Chinese gadgets...
