I doubt it really. The unwieldy USSR conglomerate is what destroyed mother Russia's economy to start with, along with the arms race with America. We actually work well together when we have a real leaders that know how to step aside and let their people work together. (see the ISS)
Loose cooperation between the U.S., Russia, and India is what keeps the Chinese from going too far.
China is Russia's only real threat for an invasion now days and even that's not much of a threat.
Any Russian claiming that America is a threat to Russia is either a knowing liar, or a village idiot.
When was the last time that anyone, much less America, even tried to invade Russia?
Ans: Left wing Germany's Democratic Socialist Nazi Party, and look how that turned out....
