The Russians should grant independence to their Muslim Republics. And then stay out of the ensuing wars.
The Europeans should do everything they can to draw the Russian people within the orbit of European civilization.
The Russians are a great people, part of Europe. Geography (and accidents of history) have kept them from participating fully in the European civilizational advance, just as, to a lesser extent, they hindered the Eastern European nations.
What "accidents of history"?
If you don't know what the Battle of Poltava was, catch up here:

Then you can appreciate this Russian joke, set at the time of the Gorbachev 'thaw'.
Three Muscovites are sitting round the kitchen table of one them, drinking, and, in the new atmosphere of relative freedom, discussing where everything had gone wrong.
The first says, "Well, it's obvious. It started to go wrong with Stalin ... that paranoid Georgian. Until he took over, things were hard on the counter-revolutionaries, but good Party members were safe. If only Lenin hadn't died ...."
They all threw back a glass of vodka, and brooded for a while. Then the second one said,
"No comrade ... you are wrong. The problems began with Lenin." (A shocked silence, then he continued.) "Yes ... he overthrow the Provisional Government ... which meant outlawing all the non-Soviet parties ... and then the other Soviet parties ... Stalin just continued the process. I'm afraid we have to blame Comrade Lenin."
Everyone throws back another glass of vodka, and broods in silence for a while longer.
Finally, the third one says, "No ... you're both wrong. Our problems began way before that, long before that." "When?" say the other two.
"With Peter the Great. He's the real culprit here."
"Peter the Great?" exclaims one of the others, "How do you figure that? He was a modernizer."
"Because," the third man said, "if that bastard had just lost the Battle of Poltava .... we'd all be living in Sweden!!!"
