What do Iran and N. Korea share, technology wise? Probably everything. Or everthing that matters from a global security perspective.
Which means there’s a real possibility Iran could be further ahead with its nuclear program than we think. Note that all of the “expert” estimates, which are themselves wide ranging, generally refer to Iran’s indigenous program. But Iran is/was just one shipment container away from having its own nuke(s). Iran, with its rich history of fighting proxy wars through terrorist organizations, may have a nuke.
It’s time we start thinking about the unthinkable. The age of nuclear terrorism may already be upon us.
