So you finally concede that the west contributed to this mess, halleluliah.
I'll add that the west contributed even more by expanding NATO (you know NATO, NATO exists for one purpose, to oppose Russia, and NATO membership includes one third of the world's nuclear powers, so, yeah, when NATO expands towards Russia, for some reason Russia gets a little paranoid - gee I wonder why?). Plus, the west have been trying to weaken Russia since the end of the cold war and installed Yeltsin and his chosen (and western backed) successor - Putin, along with setting up the oligarchic capitalism Russia now enjoys.
Realpolitik is used to explain the actions of Putin and Russia. It has explanatory power. To cite analysis to explain motivating factors in no way means I support the actions, I just seek to understand them. Understanding can also contribute to finding solutions which are less deadly, that is my concern.
While it is true that the West, and the USA in particular, dismissed Russia's concerns, Putin resorted to violence which was always a possibility. As Chomsky said "Instead of pursuing diplomatic options, Putin reached for the revolver". What Realpolitik contributes is that the motivation for Putin to choose the invasion option was explicable. What that tells me is that we should have taken this more seriously. The west's response to Russia's build up on Ukraine's border was to sabre rattle, rather than seek to defuse the situation. Putin's reaction was to unleash war.
Now the war is happening, what the west is up to? The US Defence Secretary is now saying they are gearing up to provide more arms to Ukraine. What is this, war by proxy with the Ukrainian people and their cities as collateral damage? No sign of any willingness to bring this to an end. No statecraft, no diplomacy. This, in the full knowledge that Russia has the ability, and the inclination, to obliterate Ukraine. What are they expecting, that Ukraine should attempt to win militarily rather than seek a settlement? It is clear that the western strategy is to see whether 1) Putin and Russia will withdraw at the cost of hundreds of thousands of Ukrainians dead and multiple destroyed cities, or 2) whether Russia just obliterates Ukraine. How's that going by the way, is it ok, are Ukrainians just collateral damage?
Ukraine is the meat in the sandwich. Zelensky has offered compromises - Russia has rejected them and the USA rejects any move to compromise on neutrality, Crimea or Donbass.
Meanwhile, the war continues, people die and cities get obliterated. The Russians kill and maim, and the USA adds fuel to the fire. Both sides only want peace on their terms, until that happens people are being killed.

You continue to push the anti NATO dialogue that Putin has attempted to push out, yet ignore that the Russians actions since the war began indicate that the statements around NATO expansion are purely propaganda and that the entire purpose of this war, is to reconnect all states that have Russian speaking popultaions.
You continue to push an appeasement strategy (call it statecraft if you want, but what you are calling for is appeasement) despite the fact there are numerous times when appeasement has not worked. In fact, as I pointed out before, the appeasement strategy engaged by the west with Putin is very similar to the appeasement strategy that the west pursued with Hitler in the early 1930's.
In both occasions, the aggressor (Hitler and Putin) has viewed the west as timid and weak. Potentially not since the 1930's have we seen a weaker political system around the world. No dominant political parties, all having to pander to multiple parties resulting in weak decision making both domestically and on the International stage. No governments are currently interested in wars, much like they weren't back in the early 30's.
In both occasions, the aggressor has stated on numerous occasions that they want to merge states that are naturally speaking populations (in Hitlers case German and Putins Russian).
In both occasions, the aggressor has invaded and taken control of some of those regions without any real penalty. Hitler with Sudetenland, Putin with the Donbas. This lack of response to these invasions, further instilled the view that the west were weak in those leaders.
In both occasions did those leaders then invade a country in full, Hitler with Czechslovakia and Putin with Ukraine but this is where the differences lay. Hitler knew how to invade, he had a very sound strategy for invasion, the Russians did not. This is the only bit where these different invasion scenarios differ and the west has reacted with Ukraine, they didn't do the same with Czechslovakia, in fact they doubled down on appeasement and indicated that Hitler could keep Czechslovakia, it was only when Hitler then invaded Poland did they realise that appeasement wouldn't work, and we all know how the next 6 years ended.
Appeasement is seen as weak by military leaders, and this should be where we as Australians should be concerned. A weak response from the west in Ukraine, would have opened the door to the Chinese in terms of expansion.
There is no easy answer unfortunately (and there never was, despite what you seem to indicate). Putin viewed the west as weak and unless we had shown this differently, he was always going to invade. Ultimately now, the resolve of the Ukrainians is high and all of this will result in a very bloody conflict (we are already seeing that). Russia will not leave without at least gaining the entire Donbas region and have it legitimately recognised as part of Russia (this won't be easy to do without the west seeming weak yet again), but more probably as they have indicated they want all of southern Ukraine and part of the south west to merge through to Moldova. Again this will not be an easy solution for either side.
