The old Soviet Union was no delicate flower and far from innocent. The vast majority of your problems have been internal, from the Czar to Stalin. No nation is without skeletons and Russia is far from innocent. The old Soviet Union and China hold the record for the most murders...of their own citizens.
Let's not pretend that Russia didn't expand their influence and cause great harm to many nations, from the old Czechoslovakia to Poland, Hungary, East Germany, and, you starved 2M Ukranian farmers which surely ensured decades of stories past on through the generations. Also, despite your denials, you also invaded Afghanistan.
The spreading of communism into China perhaps did the most long term damage to the world, and eventually I presume, to Russia once China becomes a prime enemy again. Nothing lasts forever, even close alliances.
There was a short relationship of convenience during WWII, Stalin should have leveraged this and embraced freedom for his citizens. You could have been the manufacturing juggernaught that China became. Alas, 40 years later, Gorbachev was rejected and viewed as an enemy by the oligarchs. Quite unfortunate. They could have brought down the military expansion across the globe if they had created a friendship with the West and we might have a cure for cancer today instead of million dollar missiles being fired.
