Do you think the launch orders go direct from the President to the "front line" button pushers?  Given that launches must be tailored as to launch numbers and targets, etc. , where does that refinement occur?  We clearly do not launch all missiles in all scenarios.  Who selects which missiles and which targets.  The President could not have time to detail a launch involving 1000 warheads.  I suspect that the chain of people ranging from generals to finally button pushers are involved.  The generals have context awareness that button pushers are not expected to.  Regardless, how would you make it better.  That is the objective is it not?
