It's not a deflection of criticism. It's used to refute attempts to portray recent events as unprecedented, incomprehensible, totally beyond historical norms. The point of comparison with both WW2 and the Cold War is that
- Russia's motivations are largely comprehensible
- Because Russia's motivations are comprehensible, this event was foreseeable, and in fact, many people foresaw it and warned that continued US escalation in Ukraine would lead to this
- The moral posturing coming out the United States Government DC is both moronic and hypocritical
- The Russian invasion of Ukraine was not "unprovoked;" it was an escalation in a proxy conflict with the United States, and
- This conflict goes back to atleast 2004
- In fact, it's not even the first military offensive in this conflict
- There is a long history here that predates even the existence of the USSR, and trying to talk about this war while ignoring, for example, a 230-year-old Russian naval base on the Black Sea and the United States' attempts to wrest it from Russian control, isn't a useful discussion. It likewise useful to understand the nature of territorial conflicts which happened nearly every single year of human civilization in Europe prior to the end of WW2, and, given that the USSR was dissolved only in 1991, and Ukraine has not even established the power to elect a government that the US Department of State disapproves of, one should give some consideration to that as well.
None of this is to say that Putin is "based" or even "morally" in the right here, only that this war is actually quite understandable if one bothers to know anything about war, nor is the United Stated Government in any kind of place to morally posture the way it is currently doing and demand that Russia treat its activities in Ukraine as no big deal at all. We all know that if Russia did the same on our border as we have done in Ukraine for the 17 years leading up to this war, or even just the prior 24 months, the same DC apparatchiks insisting that they dindu nuffin would be treating the events as a
very big fucking deal.
There are indeed historical examples of a crazy person doing absolutely crazy things with his country's military power, but the Russian invasion of Ukraine is absolutely not one of them.
