Join Rabbi Michalowicz as we study, for an hour each week, this short treatise written by Rav A. Y. Kook , that explains what brings nations to war and what are the positive geulistic aspects of large-scale wars. Written during WWI, but even truer today, Rav Kook points out the important traits of altruism, unity and much more, that are brought out davka during war. Also drawing from the commentary of Rav Uri Sherki.
