No, I mentioned it because a joint Russian-Ukrainian exercise is unthinkable now.

Ukraine shot it down, but it sure sounds like a joint exercise.

Well there you go, airtight proof.
How it is different from MH-17 (Russia blame Ukraine, found guilty in court) or this J2-8432 (Russian blame Ukraine, ...)?
