Sanctions against South Africa did barely any good at all LOL, even though they were in place for decades. Arguably they delayed the end of Apartheid which was largely down to internal forces.
The sanctions against Russia are ... patchy, at best. Some of the banking restrictions have made a difference. Others have done more harm to Europe than to Russia. Others still are frankly unworkable. Say no to Russian gas and oil? Ok good luck with that.
Plus, what is the point of just getting rid of Putin? Who is going to step into the position he's in? Nobody who you'd actually want to be in charge, that's for sure.
Plus again this cultural stuff isn't mediated by sanctions. It's just posturing, like all the halfwits who stopped selling vodka before they realised that any you get in the UK is made in bloody Poland.
