#7 Why do you constantly say that?
When the war comes home to Russia they will likely double down more.
Th Nazis didn't quit until they were crushed by the combined might of the allies. The Japanese until they were Nuked.
The Iranians never quit against Saddam. The Afghans outlasted the US after years of occupation.
Expecting internal revolution as a result of military pressure is not realistic. Most countries escalate the until military defeat or an armistice.
The current trajectory of this leads to Nuclear War.
Not regime change in Russia.
That's the wishful thinking and not supported by the pattern of history.
