Use of NRF
The NAC has been in emergency session and this Libyan business is exactly the sort of role for NRF. There is unlikely to be any push-back (except, perhaps, from Greece or Turkey because of the potential use of NRF in a Cyrpus debacle).
Oh, Trim Stab - what are these statutes that you talk about? Article V? Well, intervention in Kosovo? Was NATO attacked? OP ACTIVE ENDEAVOUR, OCEAN SHIELD etc...were Alliance members directly attacked? Continuing mission in Afghanistan? The emphasis of the recent NATO Strategic Concept is Art IV consultation - and then action, as required, based on concensus.
