The great thing about Russians, the thing that makes them such eternally awesome bad guys, is that while we stereotype them, we do so because we're kind of awed and impressed by them, and a little bit scared of them. It's quite fair to say we respect them. There have been plenty of more topical foes that have made themselves available in recent years - Iran, Venezuela, North Korea - but they're really just pissant dictatorships, ruled by crazy dudes with noisy but outmoded armies. They don't have staying power. Take Libya as an example: Back in the 80s, Qadawadayadamafi was Public Enemy Number One, they were blowing up airliners and the US was bombing Tripoli, but ultimately, what happened? Well... nothing. It all kinda blew over, everything is essentially normalized and the only remarkable part is that the same crazy bastard who started all the trouble is still in power.
In gamer terms, Korea, Iran, etc., are expansion packs. They're add-ons. DLC. They're good, they have merit, but they don't last long and they require external software to run. Russia, on the other hand, they're the god-damned Collector's Edition.
