I'd have to see actual quotes to understand what you're talking about. I've heard some of his speeches, and I read it more as a country that feels threatened, encroached upon, and encircled - something that's been a familiar pattern throughout their history.
Historically, the Russians never really had any great need or desire to conquer the rest of Europe. Most of their national security aspirations focused on their isolation and the desire to have permanent ice-free outlets to the sea. This is also figured in to their long-term goal of reclaiming Constantinople for Orthodoxy.
More often than not, it's been the countries of Europe invading and attacking Russia, not the other way around. People often forget these little tidbits of historical trivia when looking at situations like this The terrain is largely flat, with few natural defenses, so because of this, the Russians have felt the need to build up a buffer zone to protect themselves from the more powerful and (in their eyes) dangerous countries of Europe.
I'm not saying this as a justification for what the USSR did, or for what Putin is doing now, which is quite atrocious and horrific. There's no denying this, and he's effectively destroyed whatever legitimate interests Russia might have had in regards to NATO, Eastern Europe, and their border dispute with Ukraine. But despite that, I don't believe that this would constitute any conscious or active desire to conquer all of Europe. They grabbed territory when they could, when the opportunity presented itself, such as when they were on the winning side of the Napoleonic Wars and got huge spoils in return.
He may want back the same buffer zone that Russia had before, but the fact that many of those nations have now joined NATO has complicated this to a large degree. The possibility of Ukraine joining NATO was apparently completely unacceptable in their eyes, which has led us to this current state of affairs.
Putin is no Peter the Great. He's not even Stalin. If we're going to compare him to a leader from Russia's past, then he's Nicholas II.
And the only reason we're stuck in this morass is for just one reason - Russia still has nukes. There may be a solution, there may be a way out of this, but before that can even be discussed, the fighting has to stop. But with the immense damage and loss of life that's happened in Ukraine, there's going to be a lot of bad blood for generations. They might ultimately make peace, but it won't really be over.
All I'm saying here is that we should try to approach this carefully. Putin may want to do a lot of things, although I don't think anyone can read his mind at this point. He may even think he's Peter the Great, but ultimately, we're dealing with Russia as a whole, not just Putin.
Putin is ill, with some form of terminal condition. He may want to go out staying busy, instead of sit and wait. I do not see him as so pissed off by the world to do anything too drastic; nukes. He had a good life in its own socialist way.
Before the Soviet Union broke up, Ukraine had been a part of the Soviet buffer zone. It was given nuclear weapons; buffer for nuclear war and fallout. The Obama Administration, made a deal with Ukraine to remove the nukes, in exchange for protection status; against Russia. The Obama administration got the nukes, but reneged on the protection deal, which had cleaned the house and then opened the door for Putin.
Obama allowed Russia and Putin to take Crimea, with little in the way of objection. No new invasions by Russia would happen under Trump. It was not until Biden, that Russia felt safe to make another move. Biden allowed Russia to enter Ukraine; unopposed. My guess is their deal was already struck, with Ukraine now unable to defend itself; no nukes and isolated. Hillary would have been the one, but Trump surprised everyone so the plan was delayed.
Those who allowed this exchange of territory, may have thought the Putin invasion would be fast and done. They underestimated the willingness of the Ukraine people to keep fighting. But to avoid the Russian Collusion charges, that they had accused Trump of, during the Russian Collusion Coup, Biden had to pretend to turn on his ally Putin, giving Ukrainian support and some under the table cash.
Biden hated Ukraine, because they exposed his family business dealings, which Trump used to expose Biden before the 2020 election. This would lead to two fake Trump impeachments; accuse the accuser, to add smoke and mirrors and hide the Biden Family collusion evidence in plain sight. Now there is more transparency about the Biden family influence peddling in Russia, China and Ukraine. In 20/20 hindsight there was major conspiracy at the top levels of US government.
I saw a new program about Henry Kissinger, who was the Secretary of State under Nixon and Ford. He had been pivotal in opening relations with China. Kissinger had met with newly elected President Trump, before the Russian Collusion Coup and conspiracy was in full affect. He told Trump, that China was the most pressing adversary for the future, and suggested that Trump form an alliance with Russia to contain China.
Obviously, the Swamp did not like that idea, and made common sense defensive strategy seem more like treason. Now Russia and China are allies. How do the Democrats and the Swamp benefit by this alliance? Again, the Biden Family Business had dealings with both countries and they hate Ukraine, for exposing their business dealings; fire the prosecutor and blame it all on Trump. They colluded with Russia for Crimea and Ukraine and blamed it on Trump. It is good that there are now investigations.
We may need to ask Biden why he waited so long to address the imminent invasion of Ukraine, since life and property could have been spared. Who had what on Biden; source of the black mail? If we go back further in time, why did Obama wire tap Trump Towers. The wire tapping happened. It was justified by what would become the fake Russian Collision charge.
Obama said he had daily meetings with the Intel People. He had to be there as they planned this crime, that not even Nixon did. Nixon never used government resources; FBI and CIA, to spy on any opposition candidate during a presidential election. Obama and Biden out sleazed even Nixon in that sense and have replaced Nixon as the poster children of corruption. These early days; spying on Trump and the rise of the collusion coup, fake impeachments, all interfere and win an election, define the messes we now find ourselves. Did they realty try to ally Russia and China or was that unexpected?
