If the rabbis have their effect, the secular also have theirs. The motives are both religious and political. That s not religious but political. There are even economic targets behind such battling. I believe that war is emotionless.
War is the indiscriminate use of weapons.
The proof lies in the use of the atomic bomb against Japan. Those who used it are emotionless, This present state makes us regret the past. We know how dangerous is the enemy when it acts without any conscience or sensibility. It turns wild as it bombards whole residential areas. This is a political issue in the first case and not a religious one.
