You can repeat that a hundred times, but that won't change the reality. Ukraine was never close enough to join NATO. NATO refused to provide the MAP and set a certain time period for that. Since 2014 a formal cause emerged to prolong the process indefinitely as long as Ukraine would have 'disputed territories' with a neighbour.
Putin would have rejected any 'assistance clauses', because had your read their demands in December 2021 you would know that 'demilitarization' meant not only neutrality but halting any military cooperation with Ukraine and NATO.
Knowing how far the Russians interpret certain terms, if that suits them, and knowing how far they interpreted a decentralisation clause in the Minsk Accords, I am sure that 'denazification' would also mean a deeply divided state with pro-Russia regions having a say in domestic and foreign policies.
First off all December 2021 was already far to late to come up with such negotiations towards Russia, since it was evident to Russia, that Ukraine would become a NATO member. NATO NEVER backed down on it's goal to integrate Ukraine into it's network. If they had - a simple official deceleration by NATO in regards to assuring a "neutral" Ukraine would have sufficed. But NATO never offered or assured such a deceleration. Instead it continued Ukraine's integration process into NATO. - and that's a FACT.
That Putin will NEVER allow for a Ukraine to be a NATO member is also a known FACT.
What NATO refused to do, was to forward an official security assistance treaty with a neutral Ukraine - hence Putin was enabled/encouraged to try his coup attempt in Feb. 2022 which due to it's failure turned into the now existing Ukraine-Russian war. Now one and a half years later, NATO is fumbling all kind of scurrilous plans and ideas to do, what they should have already done
in 2014. (however until today still not pursuing a neutral Ukraine).
But now with Russian troops occupying around 20% of Ukraine - the Goebbels scholar doesn't want to negotiate a treaty with Russia - hence NATO is stuck again, and therefore Biden now keeps fumbling onto "individual" assurance guarantees towards Ukraine.
Individual assurance guarantees do not provide the basis needed to enact NATO article 5 - So it is still a NATO aka USA proxy war with Russia - that will enable what NATO aka (USA/Poland/UK) always wanted, latest since March 2022 that certain countries can provide NATO boots on the ground in Ukraine.
Once that happens Putin will definitely retaliate via a general Mobilization in Russia and if necessary NBC weapons - and China in order to prevent a nuclear escalation will have no other choice then, but to support Russia militarily with conventional means. That is why China forwarded a peace proposal that was immediately - even before being presented public - rejected and discredited by NATO.
Unless you have reasons to believe that China is willing to drop Russia - for the sake of NATO, NATO happily controlling Ukraine and having destroyed Russia's economy - then this scenario is going to happen eventually. Which BTW wouldn't even be a bad idea - since (see this forum) loads of Americans believe that China is no match for them due to missing "practical" modern warfare experience. And I agree that "modern practical military experience" would enable China to handle the Taiwan issue far more effective - if China would be forced to do so.
This Ukraine-Russia war isn't simply just about these two countries, but NATO aka democratic lefty&Lib countries flexing their economic and military muscles towards autocratic countries - just as they have done globally, non stop since the 90'ies. I do not recall that e.g. Iran, Iraq, Somalia, Syria, Libya, Serbia, Russia and Afghanistan have ever attacked NATO. And now this autocratic China is emerging more and more - huuuu-panic - hey guys (NATO) there is another one we need to kick into his balls - oh wait, that fellow has huge balls and nukes, let's try and **** up Russia first.
So back to "democratic" Erdogan and "democratic" Turkey - when is NATO going to subdue them? or kick them out of NATO first?
