Answer: Preventing or justifying these are different things. A Kabbalist must in any case try to prevent these actions and also justify them.
Question: Can Bnei Baruch prevent a third world war? Or must we justify this action of the Creator?
Answer: This depends on us: on how much our unity will be revealed throughout the world, on how much it will become a safeguard for the world protecting it from its egoism. The problem is that egoism is constantly growing and it ignites and invites problems like world wars. There is nothing to do here anymore. You see that Baal HaSulam wrote about the possibility of a third world war and even of a fourth world war. We hope that our actions will nevertheless prevent this and will make it possible for us to disseminate the method of unity throughout the world. Act! Act among you and around you.
