Mandatory war

In Jewish tradition, mandatory war (Hebrew: מלחמת חובה; milḥemet ḥovah), or compulsory war, refers to a war that requires the entire nation of the Jewish people to rise-up and to become actively engaged-in because of an existential threat to the Jewish nation. It is a war fought for Israel's national survival. The aim is to thwart the enemy advances against the nation of Israel, without the necessity of enslaving and exterminating the enemy, or of annexing the enemy's territory. It is contrasted with voluntary war.
