No. I don't agree, sorry. Though for the record, I upvoted you because at least you were polite.
I'll see your Aleksandr Dugin's 1997 book 'Foundations of Geopolitics' and raise you Zbigniew Brzezinski's 'The Grand Chessboard' (1997). It's quite clear, just from the text of that book alone what America's geopolitical aspirations were/are. Couple it with the PNAC documents, first published in 1997, and it's beyond debate that America's foreign policy was centered around the strategic capturing of resources, by fair means or foul. It's right there in black and white in Brezinski's text. And that lies at heart of America's deliberate invoking of conflict within Ukraine (though deeply buried beneath layers of noise and propaganda from subservient and spineless water-carrying western media and press that simply parrot the party line, in echoes so ironic of the Soviet Union itself!).
The Ukrainians are nothing more than pawns on the chessboard, same as the Iraqis, the Afghans, the Syrians, and the Libyans.
I've also heard Putin talk of Peter the Great and reclaiming Russian lands, but only in the context of Crimea, the gifting of which to Ukraine by Brezhnev in 1954 was controversial (from the Russian standpoint). I guess Russia never considered the Soviet Union would collapse, and so the transfer of Crimea to Ukraine was seen as healing and symbolic, though of little real consequence. All that changed when the Soviet Union, fell, or course. I suspect that Putin is being dishonest when he refers to taking back Crimea to protect ethnic Russians. He's more likely interested in the significant oil and gas reserves that are sloshing around under Crimean soil, as noted by this article from 10 years ago: https://oilprice.com/Energy/Energy-General/Russia-Eyes-Crimeas-Oil-and-Gas-Reserves.html
In this regard, his behaviour would not much different to that of the western nations that seek to capture and exploit Russian reserves through the break up of Russia.
I'm inclined to agree with you regarding Putin to some extent pandering to his home audience, though I do not think his actions are related to 'old wounds' such as the fall of the Soviet Union in 1991 as you infer. Sending countless thousands of Russian male conscripts to their death over such an old issue is political suicide. No, I think his actions are solely pragmatic, based on current geopolitical events as he sees them.
