Then Putin should be very scared of that risk and withdraw immediately!
He should, but he doesn’t appear to be. That puts the ball in everybody else’s court, unfair though it is.
Or the Russian people should be scared of that and force him to withdraw.
Who am I kidding, the Russian people can’t stand up to President Putin, they’re too busy listening to General Stolichnaya.
A large number of Russians are trying to protest. They typically get killed or imprisoned. It’s hard to fault the remainder for not risking their lives for a probably fruitless attempt at dissent.
It pressures the system in those cities or states, which is actual pressure to the system, just not direct pressure on the federal government. History shows you can mount pressure through local and state changes until it gets overwhelming support on a federal level.
You can make the argument there might be more effective or quicker solutions, but this is unquestionably one path toward it.
