Russia did have a record showing it to be a threat to
its neighbors....
- Conspiring with Hitler to carve up Europe.
- Invading Finland. (The invasion failed.)
- Post-Soviet invasions we've been discussing.
NATO had no record of ever invading Russia.
NATO posed no existential threat to Russia.
Putin's using NATO expansion as justification
to invade Ukraine does not make it legitimate.
They made a temporary alliance of convenience with Hitler, which they considered necessary for defensive reasons, especially in light of the British-French capitulation at Munich. As a strategic move, it kept the Germans 200 miles further from the Russian border. A lot of national leaders were still thinking about what happened during WW1, and the Russian leadership would have been no different. You can't really blame the Russians for the rise of Hitler or anything to do with what the Nazis caused. They were Hitler's prime target, and they lost 20 million of their people fighting that SOB.
As for your claim that NATO had no record of ever invading Russia, that may only be technically true inasmuch as you're referring to "NATO" as a singular body. But there are members of NATO who have invaded Russia in the past, including those nations which participated in the Allied intervention in Russia during the Russian Civil War. France has invaded Russia in the past. The Germans have invaded numerous times over the centuries. Even the Swedes have invaded Russia. The Poles have invaded Russia. The Turks have invaded Russia.
As an American, it's hard for me to fathom what that must feel like to one's national consciousness, to be invaded so many times like that throughout one's history. However, I can appreciate the fact that this may lead them to hold vastly different perceptions as to what constitutes an "existential threat."
It should be noted for the record that at no time has Russia ever invaded the United States. We did have missiles pointed at each other - and bombers and subs poised to launch nuclear strikes if it ever came to that. Good thing it never did. But they never made any claims on US territory, they never attacked us directly, nor did they give us any real cause to believe that they were planning to take over the United States - or even Western Europe.
Again, considering that the West had opposed the Bolsheviks from day one, as well as the Allied intervention in the Russian Civil War, and the perception that they had done the bulk of the fighting, suffered most of the damage, and shed the most blood in the war - along with the very real fear that the Germans could rebuild, rearm, and do it all again - don't you think it's reasonable that they had some concerns about potential hostility from the West? After all, we had guys like Patton and MacArthur openly calling for war with Russia, as well as well as total nutjobs like J. Edgar Hoover, Joe McCarthy, and all kinds of other warmongering whackos and overamped "G-men" in government and politics. You don't think they had reasonable cause to be at least mildly worried about what any of these men might do?
If nothing else, when you say "NATO posed no existential threat to Russia," that requires a lot more elaboration.
That doesn't justify anything about what Russia or Putin are doing now. Putin and his regime have crossed the line, regardless of any other position they've taken in the past. None of it justifies what he and his military have done.
On the other hand, it's a fair question to ask: If NATO had disbanded - or at least not chosen to expand - would we have to worry about the "existential threat" from Russia? Could they have perceived the expansion of NATO as a hostile act which caused them to put their guard up and take on a more antagonistic position towards the West? Do you think that's possible?
What you dismiss as "whataboutism" are actually
reasons why other countries might look at the U.S. and think "Hey, maybe these people aren't so nice and wonderful and freedom-loving as they would like everyone to think they are. Maybe they
are an existential threat to our security."
I'm not saying it justifies anything Putin or Xi have done - or what they might be planning to do. We might be past the point of no return when it comes to those guys, but I think it's worthwhile to consider how there must have been a considerable amount of fear which allowed people like that to gain power in the first place.
It's more a matter of connecting causes and their effects - both intended and unintended. In terms of cause-and-effect, I would say Putin has turned out to be some kind of "wild card" which can't really be predicted or planned for very well - although we have to figure that it's going to happen every so often. (The pandemic might be considered another "wild card" which wasn't planned for very well.)
The direction we seem to be heading at this point is possibly a realignment of the world's geopolitics which could lead to an isolation of China and Russia, coupled against a further solidification of NATO and other nations within the Western fold. However, there are a number of non-aligned nations which haven't reacted well to Western hegemony in the past, and they might be more amenable towards relations with China and Russia. So, they won't be totally isolated.
