Sorry, mister, you are wrong.
SU and nowdays Russia achive parity with US and sustain it for a long time.
Russia the best weapon seller up to the time and capable to neglect any threat from anywhere to it independency.
Playin with such a measere proxies like Georgija or Poland definitly show that Cold War doesn't end.
So Russia doesn't lose it :)
Putin's side lost the Cold War, he's just too stupid to know it! he doesn't realize that his actions sow the seeds not of Russia's resurgence, but of its annihilation.
