In this Project on Managing the Atom Discussion Paper, Philipp C. Bleek chronicles nuclear weapons proliferation choices throughout the nuclear age. Since the late 1930s and early 1940s, some thirty-one countries are known to have at least explored the possibility of establishing a nuclear weapons program. Seventeen of those countries launched weapons programs, and ten acquired deliverable nuclear weapons.

Before trashing the Iran deal — the agreement inked last fall, which limits Iran’s nuclear program in exchange for sanctions relief — the incoming Trump administration should consider how a policy of soft economic engagement with Tehran could provide Washington with strategic leverage and increased bargaining power in a post-Iran deal world.

Throughout his campaign, now President-elect Trump attacked the Iran deal, claiming that “it will go down in history as one of the worst deals ever negotiated.” The future of the deal now seems to be far less certain, as Trump fills key positions with outspoken critics of the agreement. Congressman Mike Pompeo (R-KS), Trump’s recent pick for CIA director, is well-known for his hardline stance on the deal, recently noting that it should be “rolled back.”

As early as the end of the Second World War it was recognized that nuclear fuel cycle technologies developed for military purposes—specifically, uranium enrichment and reprocessing—had major potential for peaceful applications but remained inherently dual-purpose, and if not controlled appropriately, could be diverted to military use. The very first issue considered by the newly founded United Nations was “the problems raised by the discovery of atomic energy.”

"Of course, solar geoengineering alone cannot stabilize the climate. The world must cut carbon dioxide emissions. But solar geoengineering is unique because it can help address already committed climate change—future climate change locked in due to past emissions. Cutting carbon emissions alone will not have immediate effects, given the length of time that carbon already in the atmosphere stays there."

"As world leaders gather for the fourth nuclear security summit this week, in the aftermath of the horrifying terrorist attacks in Brussels, it seems likely that Belgian Prime Minister Charles Michel will have more to say than anyone else — both about real nuclear terrorist dangers and about real steps taken to improve nuclear security...."
