Putin said back in 2005 that the breakup of the USSR was the 20th Century's "greatest geopolitical catastrophe". So yes, it is entirely possible, especially since Putin's actions have been to restore this union, albeit in a non-communist (but very likely fascist) form.
I’d like to think she meant the return of the Soviet Union, which is entirely possible
It could be possible for the Soviet Union to reform, but who in America is worried about that on a daily basis? Everyone I know is talking about China, and if you bring it up causally, everyone has an opinion. If you bring up the Soviet Union at work tomorrow, I doubt anyone will say they are rising again and taking over the world. Its just not part of the zeitgeist.
