There is one thing special about Indian military programs that I want to point out. On and Off, Up and Down is a norm in India than any other major powers. Abandoning FGFA is nothing out of that norm, therefor should not be seen as some thing specially bad for Su-57. The MRCA dragged for 17 years since the initial requirement in 2001 with eventually Rafale deal signed and killed. With that in mind, I don't see anything special this time. And I am pretty sure other program won't fare any better, including F-35 (if US really want to sell it).
