If Israel has nothing to hide then why it did not cooperate with UN investigation and why it would'nt intigate a independent investigation as per the Goldstone's report. No matter what these so called politicians or IDF say, it is pretty clear war crimes have been committed and Israel does not want to own up to them. So rightfully these issues needs to be referred to ICJ and those leaders and IDF officers who comitted these crimes need to brought to justice.
