How were Germans and Japanese leaders punished for their war crimes?

After World War II, prominent German leaders were tried at the Nuremberg Trials, where key figures like Hermann Göring and Rudolf Hess faced charges of war crimes, crimes against humanity, and other offenses. Similarly, Japanese leaders were prosecuted in the Tokyo Trials, where figures such as Prime Minister Hideki Tojo were held accountable for their actions during the war. Both sets of trials resulted in executions, prison sentences, and significant legal precedents regarding accountability for war crimes. These trials aimed to establish a framework for international justice and deter future atrocities.
