It's Russia (as the self-proclaimed successor of the Soviet Union and the Russian Empire) that owes a massive debt to the countries of Eastern Europe. It murdered millions through forced deportations to Siberia in order to replace them with Russians (half of the deported would die on the cattle trains), organized starvation (millions killed in Holodomor), and World War II which Stalin started with Hitler. Then when Stalin was betrayed, he used colonized peoples as cannon fodder to defeat Germany. And yet Russia has the audacity to claim credit for the victory and to use it for propaganda purposes, to inflict more suffering on Ukrainians.
Before the current war, Western leaders routinely traveled to Russia to commemorate the WWII victory, giving Russia all the credit and feeding into Moscow's propaganda. The West allowed Moscow to cover up the fact that it was the colonized peoples, such as Ukrainians, who disproportionately contributed and suffered for the victory.
I've always wondered what would have happened if the world had done more to recognize the Kremlin's atrocities and forced it to pay reparations to the victims, instead of sweeping Moscow's colonial crimes under the rug and sending money TO Russia to help with their economy after the fall of the Soviet Union. That was like sending money to a rapist if he released a few of his victims, instead of making him serve time for his crimes.
The millions killed during the massive expansion of the Russian Empire, in Eastern Europe, the Caucasus, Siberia and Central Asia, weren't enough for the Kremlin. Moscow murdered at least 20 million more during the Soviet Union and continues trying to savagely subjugate its former colonies to the present day. What if in the years following the Soviet Union's collapse, the world had stood firm against Moscow's gaslighting and not accepted its development of a victim complex for losing some of its colonies?
What if the world had recognized Moscow for what it was, one of the most deadly genocidal colonial empires in history. And that it owes a debt to its victims, not the other way around.
