I believe he won’t live in Russia. Maybe his son or some of his family, whom no one cares about, will live in Russia. But I think he himself will most likely live elsewhere, perhaps in some Arab Emirates or similar countries.
In response to the question: "What about Bashar al-Assad, where will he be?"
Most likely, Russia will leave and will already begin evacuating the S-400 systems provided to Assad toward the Tartus naval base. Most likely, it will leave, most likely it will leave.
Russia will leave Syria.
Firstly, we don’t know what kind of power will ultimately take shape... but the kind of ally Moscow once had will no longer exist, and there will no longer be any Russian military base in Syria. Russia’s presence in the Middle East will definitively come to an end.
I think they will eventually reach Damascus. But after that, there will be complete chaos, because this entire alliance will fall apart, and they will start fighting each other.
