If not sanctions, US willuse rhis excuse to pressure india into doing other things. Biden administration may pressure india on human rights and kashmir lockdown. Lets see how biden plans to operate.
India was way weaker economically and militarily in 90s ... still India didnt let anyone dictate ...
from where are you getting hope that India will accept wishes of a foreign nation when India is ruled by
a nationalist Govt. like Modi...
pretty sure USA in case applies CAASTA although a very thin chance as India is increasing buying stuff from USA..
just in case it applies thr is absolutely no impact on India... only visible one could be Tejas engines but India has already enough store of those engines to last a decade or more before Indian alternative comes to picture or well we could just buy from France...
