Gee. What if they had done that with Hitler?
Near as I can tell, Switzerland is on the same side now as it was during WWII.
Hitler was many things, but he didn’t rob from his country like Putin and Putin’s associates do.
Hitler was fanatical about power - that was his currency. He didn’t care too much about the luxuries.
So the tactics for stopping him were not economic.
Also note that the economic tactics make sense in todays interconnected, high complex economic world.
Hitler would have killed them
