It was in 1983 that President Ronald Reagan privately screened the anti-nuclear movie "The Day After" in Camp David and wrote in his diary of his resolve "to see there is never a nuclear war" – the ambition that fueled his remarkable series of summits with Soviet leader Mikhail Gorbachev. That very same year Barack Obama was just an undergraduate in his senior year at New York's Columbia University, still very uncertain of his place in the world, when he publicly voiced the idea that Reagan shared but kept secret, an ambition of eliminating all nuclear warheads. As reported by the New York Times, the young Obama wrote an article for a campus magazine that was entitled "Breaking the War Mentality." In it, he railed against "billion-dollar erector sets" and what he called "the twisted logic" of a winnable nuclear war. Little did the then-22-year-old Obama imagine that it would be Reagan who would start the job of reducing the world's nuclear stockpiles or that he himself would be the president in a position to carry that mission forward in the 21st Century.
