In The Nature of Man

The deep-longing desires for permanency, perpetuity, and preservation are I do believe innate in man, encoded deeply enough as to be part of his DNA.

It is in the very nature of Man to create, pro-create, build and preserve.  Not to destroy and lay waste, both his creation and himself.  Thus, we find generally no logic or justication in suicide-bombing, or even just suicide.  Or for that matter any act the default result of which is one's own demise without a decidedly greater cause.  Thus, we can justify greater love than this when a man gives his life for his friend.

I myself shudder at the thought of any destruction, whether real or make-believe.  I hate watching movies where things are blasted away like buildings or cars, or even the most petty of things.  But I beam in pride and glory at the sight of things being built and becoming reality.

We are hardwired toward creation and self-preservation.  Though at times this gets short-circuited along the way, and thus in our insanity  temporarily  set aside.

In a nuclear war nobody wins because everything is destroyed.  All potential combatants know and understand this.  Everybody is resigned and committed to this eventuality in the event of any nuclear exchange between two opposing nuclear powers.  There are no two ways about it.

Ergo, the country or people who are most committed to create and preserve are the least likely to start a nuclear war.  And vice-versa.
