No military (or the politicians who appoint and supervise them) will ever allow incriminating things to be released. Too many heads would roll. In the same way too many zionists NEED to have Israel be the good guy in all matters. It isn't. It is a nation like all others that does bad things at times and at times has destructive policies. Zionist who refuse to accept and correct faults ensure they will remain.
