It's not convincing. It's a man wrapped up in defending a worldview he's held for 5 decades against real world experiences that directly contradict it.
Putin's actions do not line up with this portrait of him as a hyper-rational long-term strategist acting on the interests of the Russian state. They line up very well with what you would expect from an aging, deeply conspiratorial cold warrior with widely publicized nationalist beliefs [0], a desire to have a legacy that compares against the likes of Peter the Great [1], and the type of delusional thinking that is the near-inevitable result of not having anyone that is willing (due to brownnosing) or able (due to corruption) to tell you hard truths [2].
Even when someone like Tucker Carlson sits down with Putin and practically tees him up to blame the war on US, he goes on ridiculous historical tangents to try to justify why Ukraine isn't real, as opposed to saying anything related to NATO. And that's not a fluke. Russian internal narratives are vastly more focused on nationalism than on anything resembling "NATO made us do this".
You also just have to look at the assassinations carried out on NATO soil - including using chemical and radiological weapons - blowing up Czech ammunition depots, etc. Years and years of unilateral kinetic escalation directly against the west. And then no response whatsoever when Finland and Sweden joined NATO.
