What I think is that, nowadays, ideologies take the place of religion in politics, which determine whether this or that is right. Whether a war is justified. Whether a coup d'état, or a dictatorship, or a revolution is right or wrong.

And if so, if the integrity is seen as being disturbed (offended) and therefore formulated as an indictment, is not a court needed to judge the case and to give a final decision whether it was needed that documents must have had to be leaked or not and whether the whistleblowers are guilty of what they are accused of, or not (or partly)?

The problem is, who is going to judge, those who judge? Because if those who are in charge of doing justice have their hands dirty, no matter to which authority you appeal, be it national or international, nothing will happen.

And furthermore, if by "US" they mean people, then it would have to be seen whether the people were offended, or the representatives of the people were offended. Also, it would be necessary to see, as you say, if the representatives of the people themselves did not offend the people with their actions. This is quite likely.

I think that if we move away from the divine, and start looking for justice in men, I'm afraid we may not find it.
