Um, Russians can very well get their hands on Asian electronics. China’s funneling what they can to the Russians, and India hasn’t interdicted Russian trade with them or through them.
Would also point out that recent Russian weapons, when tested by others, have sometimes shown that they actually do work as advertised on the box - the tandem warhead heavy ATGMs gutting NATO-spec tanks in Syria, the supercavitating torpedoes that the US is unable to duplicate (we just canceled our latest attempt) and that’s just the two I can think of right before bed.
I would not be so quick to dismiss them.
Who has NATO spec tanks in Syria?
