Looking back, one of the key lessons from modern history of warfare is that those who die in the action are only a small part of the cost. TThe much larger cost is in the millions of Lives that get soured or ruined by trauma and the psychosis of battle, damaging the minds of those who cme back from war shell shocked and trained t kill.. Any student f history knows this about war.. It litters the home font with wounded minds and spoiled lives. Yet Rummy and Bush dove into their madnesses unthinking of such costs. The mind boggles.
