Oh please. There's no way Russia's getting in. NATO requires the following as a condition of membership:
"A functioning democratic political system based on a market economy; fair treatment of minority populations; a commitment to resolve conflicts peacefully; an ability and willingness to make a military contribution to NATO operations; and a commitment to democratic civil-military relations and institutions".

There's your answer.
The fact is, now Russia wouldn't join NATO even if we wanted it to, NATO is far more useful these days to Russian nationalists, cast in the role of an enemy.
This idea that Russia is hurt because it really, really wanted to subordinate itself to a US-led military command structure, and was rejected, is laughable.
