With the exception of Poland, most of Eastern Europe suffered under Russia for a much greater length of time and to a much greater extent.
Poles were literally put into gas chambers by Germans for being "subhuman". How can anything the USSR or Russia do beat that? How does "time" change things?
If Russian occupation was so bad, why was the majority of Polish anger in the interwar years directed at the Germans?
All I see the USSR do was rebuild countries devastated by war (in some cases build them for the first time), establish new industries and share proprietary technology for free - something the US doesn't do to this day even with its closest "allies".
Even in the case of Poland, Russian occupation since the 19th century tended to be much harsher than German/Prussian and Austrian occupation during the same time period. During Germany's initial invasion of the USSR, it was common for non-Russian peoples in conquered Soviet territory to mistakenly greet the Germans as liberators.
You mean the Banderists? If so, I don't know what you mean by mistaken, they were very sincere in their welcoming. Even after they were rounded up and put into concentration camps by the Germans, they were still pro-German.
The bulk of the Waffen SS's foreign recruits incidentally came from Eastern European countries. Small numbers of Eastern Europeans even volunteered to serve in the administration of Germany's concentration camps. Every single nation that bordered the USSR voluntarily joined the Axis prior to even the onset of conflict with the USSR. Eastern/Central nations universally (with exception of Poland), both free nations and nations under Soviet control, had more negative attitudes towards the USSR than Germany.
Far more eastern Europeans joined the Red Army and fought against the Germans, what's your point here? When did Russia occupy Hungary or Czechoslovakia prior to WW2?
Well, incidentally many Chinese were living in mud huts during periods of Russian aggression. Sino-Russian cooperation is a result of 1) increasingly shared geopolitical interests and economic synergies since the mid 2000s and 2) existence of common rivals with whom each share an equally long history of mistrust and suffering. This situation parallels with the tendency of Eastern/Central European nations choosing to cooperate with Germany against Russia. The attitudes of Russians/Chinese towards one another should be more characterized as apathic but cooperative due to recognition of need to work towards common interests and against common adversaries, rather than friendly or pro-Russian/pro-Chinese.
This is the part where you start to make sense. Russia and China enjoy a close interest today because of shared geopolitical interests - specifically countering American imperialism. The historical account, as you seem to agree, for most of the last century Sino-Russian relations were poor.
In a similar manner (some) eastern European countries are opposed to Russia because of a benefit of EU/US aid payments, not because of any historical enmity. The same aid was going to Poland before WW2 from the UK to be deliberately anti-German.
I don't know how you (and the other person) can say this, and yet believe the previous point you were making. They are two diametrically opposed positions.
