The brother is both cause and effect of war

Evidence

The cause of this act of war is, therefore, the brother. More precisely, what the text effectuates within the space of two verses, between the two descriptions of Lot, is the production, the becoming-brother, of Lot insofar as he is the cause of the Abrahamic war. With this becoming, the brother also becomes an effect of the war, a consequence of the Abrahamic war. The pursuit of Abraham, his entering the war, is both condition and effect of this becoming. — Gil Anidjar, The Jew, the Arab, 332
