The war crimes trials of German and Japanese
officials after World War II demonstrate the
principle that
(1) only nations can be considered responsible
for actions during war
(2) international law may not be applied to
national leaders
(3) nations have the authority to suspend human
rights
(4) leaders can be held accountable for crimes
against humanity
The last answer is correct: many German and Japanese officers were tried and found guilty, and sentenced to death, and the sentence was executed: this shows that leaders can be held accountable for crimes against humanity
