Last week's joint factsheet offers few details, which will likely take months or years to work out. So, what's most clear about this proposed South Korean sub? There are choppy waters ahead.

Trump's surprise announcement about a South Korean SSN leaves us with far more questions than answers. How would South Korea build and fuel an SSN? Why does it want an SSN in the first place? What implications for the US-ROK alliance and how could it impact geopolitical and regional security?

How can the intl community best address these challenges, both to deescalate the Iranian nuclear crisis and forestall any lasting damage to broader nonproliferation efforts? I offer some thoughts - there are no easy answers, but the task could not be more urgent (3/4)

I argue that the U.S. and Israeli strikes, Iran's new IAEA law, and Iran's potential withdrawal from the NPT not only increase the likelihood of further conflict, but also stand to inflict widespread damage on the nonproliferation regime (2/4)
