Here at Best Defense we've never really gotten into VUCA, an acronym apparently developed at the Army War College to describe the "Volatile, Uncertain, Complex, Ambiguous" environment that many think we will face in coming decades. It actually brought to mind a woman I dated in my senior year of college for a few crazy weeks. It was a learning experience, OK?

But I think the acronym-makers missed a chance here. If they added "Lethal" in the middle and "Novel" at the end, then we could face a "VULCAN" challenge.
