The deck, making no effort to put a cheerful face on the business, opened with old stock footage of mushroom clouds rising from nuclear detonations. The voiceover was in English with Hindi and Punjabi subtitles. Dates and words were superimposed on the fireballs: USA 1945, USSR 1949, China 1964, India 1974. "Nuclear bombs have existed for the better part of a century, and yet they have only been used in battle twice, at the very beginning of the atomic age, at Hiroshima and Nagasaki." Pictures now of devastated Japanese cities and maimed civilians. "It is extraordinary in all of human history for man to have developed a weapon but then voluntarily refrained from its use. Why? Because it was understood that the consequences were undesirable." Pretty dry understatement there, as they were now watching clips of old sci-fi movies showing grisly post-nuke effects and horror-show makeup.
