Seventy years ago, as it is happening at the present, children went to war. During World War II, child soldiers fought throughout Europe and Asia. Children frequently fought in insurrections in both the Allied and Axis forces. Hitler Youth, SS Youth Division, German People’s Army, Jewish Resistance, Soviet Union’s Red Army, Japanese youth military groups,... etc, were some of the ways to fight during the war.
