You've missed the main point he was making: that the situation in Ukraine was partially precipitated by the U.S. meddling. Victoria Nuland, the Under Secretary of State, was caught on tape 'engineering' the next Ukrainian government, a fact inconveniently leaked out

There's probably a lot more where that came from.
From Putin's perspective, he witnessed a democratically elected government being overthrown and a new, unfriendly government installed, pulling the country toward NATO. He clearly communicated that this was unacceptable and that he would act accordingly. The US/UK/EU assumed this risk, but in my opinion, it was a miscalculation. Strictly speaking, there is no benefit for the US in admitting Ukraine to NATO; it's a situation that is more dilutive than accretive. What the West should have done was to take NATO off the table and slow-walk the EU talks. In 20 years, Ukraine could have been a member of both. However, under the current scenario, Ukraine might lose millions of people, become completely obliterated, lose territory, and probably end up as a failed state within the next decade. That's realpolitik for you.
Additionally, Putin didn't attempt a full-blown invasion. You don't invade a country like Ukraine with less than 200,000 soldiers—it's not feasible. In my opinion, he aimed to solidify control of Crimea, secure the two eastern regions, and intimidate Zelenskyy into resigning or accepting quick concessions. However, it didn't work as the Ukrainian Army is incredibly strong, resilient, and well-armed/trained, effectively countering his actions. That was Putin's miscalculation, and that could have been the time for peace talks and ending hostilities. The West pressed on, Putin regrouped, and the Russians, as they typically do, became stronger as the war went on (see WWII, 1941 vs. 1943, etc.). The reality is they are winning the war and no amount of wishful thinking could change that.
I am not pro-Putin; I am pro-U.S., but I realize that we should keep our powder dry for issues that matter and not get tangled into yet another useless conflict.
