Don't hide behind the nation and lables, make that person who did bad things accountble for crimes.
The one who does order someone to do never guilty because evervy human have common sense what can Do and what not against other people.
World will not deal and not punish those that's why we keep seeing how people complaining.
Punishments are too soft too off course everbody will do bad things because no punishments.
The law is only effective or potent when the poor or powerless are involved. People who have caused war or engaged in killings during conflicts usually face trial in the International Court of Justice. Warrants of arrest are usually issued to force them to appear before the court in Hague. Since the creation of this court, only suspects from poor nations have been tried convicted or cleared by this court. Even when a Warrant of arrest is issued against some powerful leaders, most nations don't enforce it.
