That strategy has, I think, never worked in the history of dictatorships. It probably won't start working now.
It at least has a very low cost so even if it has marginal success it seems like an easy call. However, it can’t stop there. In this case, unfortunately, it has to get worse before it gets better for the average citizen in Belarus.
If the west is serious about taking down foreign dictators it needs to man up and start assassinating them, either with hit squads or drone strikes. No pussyfooting around and hiding behind the hope that locals will get the blood on their hands so the foreign bureaucrats don't have to. And if the EU isn't willing to do that, then it should be trying to do what it can to make life better for the Belarusians, just like a doctor would try to help a sick patient even if they spent a lifetime smoking and thus in some way might have some culpability for it.
