They only do when dire consequences have already been imposed and that kinda pisses me off.
Take for example the recent blacklist issued by the OECD. They imposed sanctions against countries that are continuing to act as safe havens of money being laundered by drug lords, dictators and corrupt officials of various governments and other types of dirty money.
Because of such states, dictators and drug lords continue to be in business. Let's hope that that the rest of the globe act in harmony and weed out these channels of corruption, murder and societal decay. Otherwise, this century will be marked by the triumph of evil.
