Nuclear risk, American hubris and great-power competition

Project Syndicate: In your new memoir, A Life in the American Century, you describe implementing US President Jimmy Carter’s policy of ensuring that plutonium formed from uranium in nuclear reactors was not reprocessed and reused.

Joseph S Nye, Jr: The beginning of the 1970s was marked by widespread fear of oil shortages and the belief that the world did not have enough uranium to power all the nuclear reactors we would need to replace the oil. We were headed for an economy based on plutonium – a weaponisable material.
