Who are the world's biggest war criminals?

Identifying the world's biggest war criminals is subjective and often contentious, but several figures are frequently mentioned due to their involvement in severe human rights violations and war crimes. Notable examples include Adolf Hitler for the Holocaust, Joseph Stalin for the Great Purge and famines, and leaders like Slobodan Milošević for atrocities during the Yugoslav Wars. More recent figures include Syrian President Bashar al-Assad for his government's actions during the Syrian Civil War. These individuals are often tried in international courts or condemned by global organizations for their actions.
