Why was the night and fog decree a key event in ww11?

The Night and Fog Decree, issued by Adolf Hitler in December 1941, was a key event in World War II as it authorized the secret arrest and disappearance of individuals in occupied territories who were deemed threats to the Nazi regime. This decree aimed to instill fear and suppress resistance by making political opponents vanish without a trace, contributing to the broader campaign of terror during the war. It exemplified the brutal methods employed by the Nazis to maintain control and eliminate dissent, ultimately facilitating the regime's atrocities against civilians and partisans.
