@lmsvater > But Putin has too many supporters and they only realize what's going on when they can't maintain their standard of living.
Again, this just doesn't work. You look at this from standpoint of well-off democratic society.
This is not the case. The core of Putin supporters are poor people. These are who go to war, join army on contract, work as the police and such. They already don't have high standards of living and reducing it further won't "make them see". They will just believe that the West is out to get them.
Look at North Korea, look at Iran and how wonderfully sanctions worked there and "made people see".
In fact the effect of some of the sanctions is the opposite - e.g. blocking payment systems makes it harder to use international services which means people have less access to information. Before the war I planned to run a public Mastodon node for Moscow. Sanctions made it prohibitively expensive for me. Basically they just hand Putin more control and influence over the Internet.
