Putin has huge internal security apparatus backing him up. He does not give a flying fuck about what people think and will not hesitate to suppress any potentially threatening activity with overwhelming force.

If you think that you can sanction / starve Russia to the point that simple people will organize, revolt and depose Putin I think you live on a different planet.

The only force that can really depose him are some competing elites assuming they have backing from enforcement agencies / military. I am not sure how you can sanction / bribe those into action.

Personally I think the West had quite a few years to sort things out between Russia and Ukraine. I think it was possible. I do not have any real proof but I suspect that instead of trying to find some meaningful compromise they were playing hard ball and are now reaping a "reward". What to do now - I have no frigging clue as the situation is out of control.

As for the subject of "suffering" - purposely starving the whole nation and keeping people hostage I think is what scumbags do / advocate.
