You're sort of asking all the wrong questions, lol!
First of all, Russia isn't the Soviet Union, that needs a clear separation at this point.
Secondly, you were never really 'the enemy' per se - you were the main rival. If you imagine that global supremacy was the goal, the USSR viewed the USA as it's rival for that goal and projected it's own aspirations onto you, assuming you wanted the same thing. During the cold war, it had to control its own people by some means to assure 100% loyalty and productivity - it did this by using fear, fear of being conquered by the USA and NATO, fear of nuclear annihilation by the USA. It created an outside source of fear so that its population wouldn't question what was happening at home. You could never have had peace with the USSR unless it had achieved its goal.
Russia is completely different - Russia started off quite reasonably thinking that, as the USA had won the race for Global Supremacy, Russia could stop competing and find its own part to play alongside other countries and genuinely work together. You'll notice that Russia was careful, when it did get back on its feet, to avoid intruding on areas in the USA or NATO's sphere of influence, like building up a presence in the Arctic, for example. Then South Ossetia broke away, Georgia invaded and Russia saw itself as being able to become a peace-keeping force, as it had done in Kosovo. Unfortunately, this time the USA treated it like the USSR, as an enemy, as an agressor, and things have really gone way downhill since then.
The last group of people America actually conquered was the American Indians in the 19th century, The Germans were merely defeated and occupied by the US for a few years and then put back on their feet, a German government was established and elections were held. Germany got Democracy by being defeated by the US and its allies (except for the Soviet Union), I can think of a lot of worse things than being defeated and occupied by the United States and then set loose, a nuclear war is one of them. If the United States was such a terrible country, then why is the average German standard of living higher than that of the average Russians? I suspect Germany is a lot better off for having been defeated by the United States than it would have been had it won World War II. Do you suppose the Russians feel that their lives would have improved much if they conquered the World? They'd be still stuck with the same political and economic system that doesn't really work for them and they'd be dragging down the rest of the World to their level.
There are actually two groups of Russians we need to consider, there are those leading the government and there are the rank and file citizens of Russia. The rank and file usually does most of the dying for their leaders ambitions, the only people who actually benefit from expansion of the Russian Empire are those running it, the rank and file spill their guts on the battle field and if they survive, they get to look at a larger map of Russia back home, but their lives are basically the same, their standard of living doesn't improve, all they actually accomplished is forcing some more of the world to live like they do, that is their victory.
I want to correct you one one thing, the United States doesn't have a sphere of influence, it has never forced anyone to be its ally, unlike the Soviet Union, which had a whole bunch of fake "allies" under its control called the Warsaw Pact. The Soviets basically invaded and set up governments under their control so they'd look a little better in the eyes of the World, the Soviets were basically trying to present themselves as "anti-imperialists" as they went about building their empire.
Most East Europeans resented being forced to live as the Russians do, under Stalin's and his successor's diktat. The moment they got a chance to break away, when the soviet grip loosened, they did. The Soviet/Russians did not make a lot of friends in Eastern Europe when they did what they did. Now what does America's "sphere of influence" consist of? A bunch of nations that want to remain independent and free, countries like Poland for instance Poland and the USA make natural allies, because Poland wants to remain free of Russian control and influence, and the USA wants Poland to remain free of Russia's control or any other country for than matter to prevent Russia from getting bigger and being more of a threat. American foreign policy consists of helping smaller countries avoid being swallowed by larger countries, not necessarily for altruistic reasons but for a very selfish one, the United States doesn't want its rivals getting larger and becoming more of a threat.
The United States is already a superpower, it doesn't have to do anything and doesn't have to conquer anybody, it already has what it needs, and their is a steady flow of immigrants coming to its shores, and plenty of room for them all, only 5% of American land is developed, that is urban or suburban, the rest is farmland or wilderness, and the land area is comparable to China's except we don't have 1.3 billion people, and much of our land is more arable than China's. All the United States has to do is defend its position in the World, while countries like Russia believe they have to conquer somebody in order to be a great power. The United States tries to prevent those conquests by other powers trying to be "great" that way it can stand secure.
if Russia simply wants to expand and develop its economy, there is nothing we can do to prevent Russia from rising like Japan or Germany, but Russia is old fashioned, it sees "greatness" as how big a spot it occupies on the World Map, that is really unfortunate, so Russia feels it must conquer Ukraine and grab up as many former Soviet Republics and former Warsaw Pact countries as it can, all the while the average Russians life is not improving, its going the opposite way in fact, because Russia's aggression has made other countries less willing to trade with it.
I have nothing against Russians, if they mind their own business and don't seek to conquer others, especially my relatives in Poland. I've met some nice people from other former Soviet Republics such as Ukraine for example, some of the hard line Russian nationalists want the independent country of Ukraine to disappear. One thing I do agree with is its hard to do a World War III campaign or setting without getting into politics, World War II was political, it was the politics that determined the war after all.
