The USSR didn't break up, they are secretly in underground bunkers
Too much Call of Duty 4, eh.
"The soviet union broke up" please, Russia didn't lose any of its power in the process
The Soviet Union fell when their economy crashed in 1991 under Mikhail Gorbachev. The Next president, Boris Yeltsin, only made things worse. Therefore, the USSR ceased to exist. Even if it was trying to rise to power again, Yeltsin would have made it collapse.
