I think we seem to be fast approaching such a situation. As it is, I don't see the prospect of another FA of Russian lineage in our Air Force soon except the Su 57 & that's a big if too. They will raise their objections and be shrill about it too given their loss in revenue. It's up to us to get decisive & put our foot down when necessary. Brandish at them a few billion dollars worth of a deal in any of the other segments and threaten to give it to some other vendor if they aren't accommodative.Go to the Israelis and take their help in integrating missiles, or an AESA; let Russia do or say what it wants
I personally think there a lot of ways we can get them around, if we want to. I fear the problem is more within in that we still haven't decided what we want as part of the upgrade and from whom we want it from.
