Perry Treadwell approaches the warrior nation hypothesis as a biological scientist: what is the evidence? Did Americans respond to conquering the continent by selection of a more violent culture? Do American present day policies, politics and pastimes reflect this selection? Is this culture influenced by the "wild west" images of cowboys, shootouts, Indians and cavalry? Does American heroism means sending out youth as cannon fodder? The reader must judge for him-herself from the essays. Treadwell is the author of Boys into Men, Grandfather stories, From Sea to Shining Sea, Last Negro in County is Dead and God's Judgment? Syphilis and AIDS
