As this is a long interview and I have a weak stomach, I have seen this in bits and bobs. Interestingly, Russian friends have told me he always talks like this, a rambling ahistorical flim-flam used to justify his worldview, but western observers did not know before this interview. Whatever the historical nature of his worldview, it is a fixed one resembling Adolf Hitler's fumigations whereby all his crimes are easily justified by the transgressions of others proved by pseudo-history especially dealing with the actions of his rule. The resemblance to Hitler´s occasional talks to supporters and cronies is marked.
Even if Russian is not understood, his means of talking in his official capacity, to my mind, resembles Trump's. Short speech patterns with sentences, phrases and clauses often left in the air-really the declarative functioning of bar-room bores. While Trump gains rhetorical energy through rising phrases, his voice becoming louder towards the middle of a clause or sentence, and giving power to what is often nonsense, Putin gains energy through historical observations, or, where recent history is concerned, complete lies, which distract from his one tone discourse.
Comparison with Hitler is valid as he used the power of his voice to promote propositions while distracting from contradiction. Like Putin, he attempted a rewriting of history through repetition and rhetoric, although Putin's delivery is relaxed and low key masking the sheer banality and brutality behind his discourse. Surrounded by yes men and the weak minded, he has got used to being listened to with no one shouting 'rubbish'. A mafia boss who thinks he's a scholar?
