Would you not agree that government ministers who can impose economic sanctions on the Lukashenko regime have more power than regular voters since they sit at the top of the power hierarchy?
They might, or they might not at all. Who knows what government can truly influence that man. Examples plenty of countries being sanctioned that simply ignore the sanctions and do their business elsewhere, or not at all, even if that means their people suffer the consequences.
I definitely support asking our governments to pressure their government. But I wouldn't ignore the fact that people in Belarus are be the ones that might be able to affect real change in Belarus.
Economic sanctions will severely hurt individual Belarusians, who are the ultimate consumers of those trade products. It is hard to imagine sanctions improving the quality of life and ability of protestors to communicate with the outside world.
Separately, I would expect American sanctions to push the country towards increased trade with Russia and China -- who are both allies of Lukashenko.
