In August, 1945, the United States exploded a sin­gle nuclear fission bomb over Hiro­shima and another over Nagasaki. Both cities were destroyed, 125,000 Japanese were kil­led outright, and within months another 100,000 had died from in­jur­ies and radioactive fallout. Yet, today, each of our Trident sub­marines has the firepower of about 200 Hiroshima bombs, or eight times the fire­power released in the entire six years of World War II!
