It has everything to do with what you wrote as you claimed that the Feds should prevent extinction and not interfere into wars. I just asked a natural question, what if they overlap, what if a war could lead to self-annihilation.
Bill has provided a clear answer to this question. He distinguishes between natural and cultural catastrophes and advocates interferences in the former and non-interference in the latter case. You on the other hand refuse to think about the issue. So much about not making sense.
