Interesting to learn about this old treaty.
But is this treaty still in effect? I don’t know all the specifics of how the Soviet Union formed and combined Russia will many other countries, including Ukraine.
I also thought there was an agreement, in 1990 or 1991, in which the Soviet Union officially dissolved, and Russia recognized independence of the countries of the former Soviet Union. Was that a formal treaty which would still be binding today?
No. The treaty was nullified at Versaille.
