You argue that "... a charge like war crime is so serious that it cannot be left to the political inclination of individuals for the commencement of prosecution." I wonder what a person like Simon Wiesenthal would have thought of this principle? Let's be clear here. There are international laws enacted against war crimes, but sadly many crimes of war still go unpunished. Of course it would be best if these crimes would be prosecuted in the countries where they have been committed. Gideon has illustrated clearly how the Israeli state is dragging its feet. Unsurprising because people like Dichter are carrying out state policy. I disagree with you that only organisations or state bodies should be involved in hunting down and charging war criminals. It often takes the personal efforts of individuals (Wiesenthal, Klarsfeld) for a prosecution to happen at all. I agree that there should be certain safeguards to prevent abuse, but I have not seen any examples of this yet.
