An exact statement Anders.

100 people may have been tops for a hunter gatherer group.  So we are 
talking 10 exp 6 to 10 exp 7 larger groups with weapons far beyond rocks 
and hunter gatherer psychological traits.

Developing technology (and in some places birth control) has kept the 
hunter gatherer war reflex at bay--with minor exceptions--for the last 60 
years.

Nanotechnology and related *might* come along in time.  But if it does not, 
we are in for an orgy of wars..
