That’s the same talking point the far right uses for why the US shouldn’t get involved in Ukraine because they worry about a destabilized Russia if Putin goes away.
It’s some sort of dictator insurance policy. The idea that they are there because the country will likely just do it again but worse given the chance.
I haven’t heard that talking point. It seems like a pretty stupid strawman. Nobody is proposing removal of Putin by force, as far as I know.
