- Europe Should Not Let Nuclear Nonproliferation DieCommentary
Amid uncertainty caused by the Iran war, the global drive for nonproliferation has stalled. With Europe diplomatically marginalized and countries reassessing their nuclear options, efforts to curb the spread of nuclear weapons risk becoming irrelevant.
