The United Nations has played a critical role in Libya’s modern political history, starting with a stewardship process that led to independence in 1951. It prepared a partial stabilization plan after the 2011 NATO intervention, which unfortunately was not imposed as a precondition for that intervention, and established an essential humanitarian channel to the outside world following the revolution. But for the last months, UN attempts to broker a unity government via its Libya envoy, Bernardino León, have worked against this legacy. Despite good intentions, recent UN efforts to seal a deal at almost any cost ironically have exacerbated Libya’s vulnerability to outside spoilers, notably ISIS.
