Three Alls policy
The Three Alls policy (Japanese: 三光作戦, Hepburn: Sankō Sakusen; Chinese: 三光政策; pinyin: Sānguāng Zhèngcè) was the Japanese scorched-earth policy (Japanese: 燼滅作戦, Hepburn: Jinmetsu Sakusen) adopted in China during World War II, the three "alls" being "kill all, burn all, loot all". This policy was designed as retaliation against the Chinese for the Communist-led Hundred Regiments Offensive in December 1940.
