Not even a little bit. The Russians were shitting a brick by the end of it. And by it I mean the end of the German offensive into Russia. Allied supplies and the western front were the breathing room Russia needed to stay in the fight. Otherwise winter ends, Germany reestablishes its supply lines, and Russians continued to get slaughtered at an almost record pace that could only be beat by organized mass suicides. There is no world in which Russians were winning that war without help and to even say they "won" it given their absurd body count is still laughable. They were saved from death from others is a more accurate description of their state of affairs.
2. Yes we are. And modern day Russia is starting to look about as well equipped as WWII Russia given their economic issue. Cold War Russia might have a point but modern day Russia is not a global military threat. China is the much more important long term threat military speaking because while Russia is declining/struggling to maintain the status quo China is making steady progress. The U.S. navy alone could probably take on most of the world in a conventional war.
