Sam Aronow gives a history of the chaotic times which opened the gates for Rome to conquer the Middle East. Civil Wars fought among and between Jews caused the internal collapse of Judea. From these disasters the Sages learned that the primary purpose of government: to prevent any and all Civil War plagues. A Civil War merits the status of a Torah curse from HaShem. Comparable to the plagues which destroyed Egypt in Moshe the prophet’s lifetime.
