No, Russia's capability does not approach that of the Soviet Union (USSR).  Vladimir Putin has many times stated his intention of restoring Russia to the power of the the old Soviet Union, and wants to reclaim the countries that were formerly part of the USSR, who have since gained independence.   He has sent troops into some neighboring countries with that aim in mind.  Not all of them want to be reunited, but may not be able to defend themselves.  In some cases they appeal to NATO for help.   This is history, please do some research.
