I don't think you're entirely wrong, but I think there are two factors at play here:
1. The USSR's power projection was really good because it's really hard to convince people to fight for capitalism. For communism, on the other hand, you always have a million volunteers.
2. The USSR's military credibility when it comes to a land war in Europe was based on the fact that they were preparing for a near-home or home defense scenario. So, instead of investing in expensive fleets, aircraft carriers, and bombers, they invested in tanks, close-support aircraft, and anti-air stuff. The Atlantic would prevent the US from effectively responding to massive columns of tanks, since tanks are very heavy and hard to transport and supply. However, it also means that the USSR wouldn't be going anywhere with its massive war machine. It wouldn't have any ability to threaten anything outside of euroope. So the obvious result of any conventional war would have been the US conventionally bombing every Russian city to dust.
