Russia yearns for the good old days.

Russia isn’t the Soviet Union, it was a part of the Soviet Union, and a member of the “Commonwealth of Independent States” that nominally succeeded it. My understanding is that treaties were reaffirmed with the individual states.

Does every non-binding commitment to be Soviet Union apply to Uzbekistan? Estonia? Georgia?

What about when the desires of Estonia conflict with the Soviets?

What about when the interests of the United States and other big NATO states conflict with the commitments to the various Post-Soviet states?
