Maybe the Russians will see opportunity in an accord with Germany that can be turned against Germany this time to Russian advantage.
I believe that a lot of Russians were VERY unhappy about the reunification of Germany. Although East Germany was a Warsaw Pact loser and money-suck, it kept West Germany reduced and weak. Now, I’m sure that they would rather see a “friendly” reunified Germany than an unfriendly one to their west.
I had read that they have the bones of 50,000 German soldiers are stored in a warehouse in St. Petersburg or Moscow, for use in the event that the Germans invaded again. The plan was to strew them on the invasion path to demoralize the invading army. The German government had been negotiating for their return for some time...
Any agreement between those two is a precursor to war.
The first "accord" didn't turn out well for either side.
