A man who made people sit VERY far away from him and went into hardcore isolation in 2020 due to fear of covid is clearly signaling he cares very much for his health/life. I think its a 2 for 1 thing though. He cares for his life and his reputation, and this is a threat to both. Maybe he would be ok with dying if he was the great Hero of Russia, but this wouldn't be that.

I also don't think he would be safe at all in any country. Russia has openly poisoned people in Great Britain, you think they would care about some Middle Eastern country? And it's likely Russia who would go after him. And people would laugh and say it's just desserts, even people in the international community. What bribes can he grant once he is out of power that would make people want to protect him? Only thing I could see is if he gave nuclear weapons to some countries in violation of the Nuclear Proliferation treaties in exchange for protection.
