The Indians will still likely get it. They have way too much Russian hardware to start caring about things like that.
Especially now that Chinese weapons are rapidly evolving and Pakistan is getting them.
Vietnam will also simply not care about US sanctions. Or Algeria.
Since the US claims the Russians cannot make military avionics without their oh so precious semiconductors, then they should not mind if Russia exhausts their chip stockpile with exports since they can't get more no? You will see how hollow this idea the Russians need US/EU/Japan/Taiwan electronics is.
Couldn’t India technically go to Israel for upgrades? Romanian Mig-21Bisons have Israelis radar upgrades.
