IMO , if GoI is determined to get the Su-57 , they'd be signing a huge deal with the US for defence & purchase of oil & NG among other items.This kind of bullying may work against Algeria(or not!), but certainly not against India. We had two options:
1. 114 F16Vs as MRFA with 60 F-35s as 5th gen stop-gap.
V/s
2. 114 Rafale as MRFA with 60 Su-57I as 5th gen stop-gap.
With IAF selecting 114 Rafales, it's clear which direction we're headed towards and there ain't a thing Uncle Sam can do about it.
That bonanza defence deal has been pending since Irish Joe's last year in office. I can think of the Predator drones , additional P-8i , MH-60 R hptrs & so on , top of my head.
This should succeed the signing of the FTA & possibly us hosting the Quad with Trump in attendance. This would be a trade off against the US invoking CAATSA .
The argument in public would be our deal with the Russians preceded the passage of CAATSA by the Congress , hence this Act doesn't apply to us which is a fact besides India not seeing itself bound by unilateral pieces of legislation by other countries unless it's by a globally recognised body like the UN.
In any case this will follow the signing of the contract for Rafales. There has never been any sense of urgency with which the MoD / GoI has operated especially under placeholders like the current incumbent. Why should there be any now ?
Besides we aren't getting it in any case by 2030. All our preparations are geared towards taking on the Chinese in 2040. There's still 14 years to go for 2040. Plenty of time on our hands.
Alhamdulillah !


India: US Warns Of CAATSA Sanctions Over Russian Stealth Jets!



"sit, go fetch, roll..." or like a RC toy 
So it cannot be bought. Moreover it is too much to be absorbed by current state of our MIC.
