You do realize you're trying to deal in good faith with a bad faith actor ?
I mean, he's been actively and deliberately twisting facts to support a pro-Russian narrative since the original invasion of Crimea, with the full propagandist "Russia wouldn't ever attack Ukraine, they're brother", "It's not Russian soldiers who occupied Crimea, it's native people who want to join Russia", "these were Russian soldiers that were welcomed by the local population" and so on, with the chain of false argument being string along with no recognition of previous lies and just 1984-like redefinition of the past on the fly ?
