Winners of the war conduct the trials, not the losers.
may i gently suggest that you go look up the "memoranda to all serving commissioned officers", realative to the commision of WAR CRIMES, by GEN Winfield Scott, dated 1848. his comments are more "literary" than mine.
btw, under the Law of War, any POWER "having knowledge of any crime in wartime, which is committed by ANY nation's military forces MAY be adjudicated by that power."
