Agreed.
I also believe that sovereignty should have no say if crimes are
committed against humanity or like cases of murder.Orders from a
state have no legal weight in a court of law in this case, as cited
from the Nuremberg Trials.
In war, each commander must realise the gravity of the situation
and always remember to check the validity of the command issued
down.War Crimes Tribunals are not made for show, and when you fight
a war, you'd better think of how you can come out of it legally
unscathed too.
