Has sanctions ever worked?
Seriously, the success rate of sanctions must be pretty low. And even if they were successful, they only hurt the average citizen not the upper class.
Europe has been violating the sanctions and importing Russian energy all along.
Seeing as the European countries of Bulgaria, Germany, Greece, Poland, Italy and Hungary still rely on Russia for energy products, it's highly unlikely.
If sanctions don’t work why does Russia have to use tankers that sink all the time? Because the best tankers are sanctioned.
If sanctions don’t work why doesn’t Russia have potatoes? They have run out of spuds!!
