Not at all, but he will likely be less powerful and receive a country with a collapsed economy, a decimated military, no diplomatic leverage, a huge pile of sanctions, and probably very difficult internal conflicts.

It still sucks that they have nukes (probably even more so, since selling them to rogue states gets quick cash to deal with these problems), but Russia will otherwise pose no threat to anyone but the Russians who didn't make it out if there, at least for a decade.
