The International Criminal Court uses a prosecution-only approach. And by putting their fate in the hands of outsiders, countries are really dodging responsibility for actions taken in the name of that country, in the name of the people in that country, by the people of that country themselves. That is, I think, fundamentally the wrong direction to go in.
