If there were forces from Nato countries there, the notion of them operating under the US dominated Nato chain of command would be unacceptable for the Lebanese. As well one would imagine that even the 'new' Nato clients er sorry 'members' wouldn't be lining up for a gig that could result in them becoming US controlled cannon-fodder in a warzone with no US forces at risk.
