As for Elon Musk here, I personally dont think hes very dishonest(for a billionaire), I think its just few people understand his true motives and hes partially delusional in his actual motivates IMHO. His sudden involvement in sovereign affairs seems bizarre and foolhardy until you really think about it.
Musk doesnt care about money, which most people cant get past and assume he must be because hes a billionaire. Hes motivated by one main thing, making earth interplanetary to "save the species". He was obsessed with sci-fi as a kid, and that has heavily influenced his thinking, and his goal as he sees it is to buy time for earth, and start colonizing other planets. Whether hes crazy with that is a separate discussion. But Tesla is his bid to both extend the lifespan on earth and make enough money to fund Mars rockets. Its also why he talks about underpopulation and pushes those. Spacex is his bid to make humans interplanetary. However there arent enough rocket launches to make enough money to fund that. Starlink was then born to both get more launches and experience for the rockets but also make the money SpaceX cant make to fund the Mars venture.
And that brings us to Musk getting involved with bad advice when it comes to sovereignty. He feels hes making good progress on all fronts. But the one thing that keeps humans from going interplanetary is a nuclear war that destroys the planet and thats what hes terrified of right now. Its what he cant control, what he sees looming, and hes desperate to stop it. While he does have a sense of right and wrong Russians seem to strangely lack, as far as he sees it any peace at any terms is far preferably to the moment a nuke launches. Its too soon. He was supposed to make humans interplanetary BEFORE this happened to save the species. Thats why he proposed and desperately hopes for a terrible "peace".
