Nuclear and chemical weapons, artillery were invented by West. The US remains (hopefully continues so) the only country that used the nuclear weapons against another country. All defunct European powers routinely engaged in slave trade, drug trade, ethnic cleansing (in very inventive ways sometimes as the Americans nearly exterminating the entire bison population which was the main food source for Native Peoples).
...and yet, Russia today is overtly and unapologetically engaged in genocide and ethnic cleansing in it's invasion of Ukraine, not to mention what the regime has been doing in other regions such as Georgia.
If you seriously had a problem with whataboutism involving the US and Europe, you'd be seriously pissed at what Russia has been doing for over a decade. But here you are, making excuses to whitewash Russia.
Also, you may want to look up the definition of genocide. The parts of Ukraine that Russia took are almost 90% Russian ethnically.
Somehow you don't hear any calls for Ukraine to return the parts of Poland that were attached to it by Comrade Stalin either. They've been a part of Ukraine for barely longer than the parts of Russia where the fighting is happening.
So yeah, whataboutism.
- In 1940s, USSR totally resettled all Crimean Tatars to Siberia, and only in 90s they got permission to return home. For comparison, imagine US will resettle all people from Florida to Alaska - you will not name this genocide?
And yes, resettling of peoples, was typical for USSR, and Russia was main power in USSR, even when prime ministers was from other parts of Union, so demography policy was pro-Russia. For example, up to 1990s, Russia constantly resettle Russians to Eastern Ukrainian regions, and same way, now Kazakhstan, and other Asian exUSSR counties have large share of ethnically Russian population.
