Also, you seem to be putting the actions of Putin (and the consequences of allowing him to get the country to this state) on to Europe and NATO. The fact is that these sanctions would not be in place if Putin didn't invade a neighboring country for illegal annexation (specifically, Russia violated United Nations Charter Article 2, paragraph 4).
I'm sorry to tell you that mass protests aren't enough. As long as the Russian people are complicit (for example, by continuing to contribute to war efforts at their oil refinery jobs) and continue to allow Putin to govern, they will suffer.
