"So this is our war?" Amy Davidson asks for some clarity:

Will it make a difference, if Qaddafi falls tonight, if we called this war a war? (Apart, but one hopes never so far apart, from the rule of law mattering, that is.) Maybe more than ever: if we are not honest about our role, then how will we assess our responsibility for whatever regime takes Qaddafi’s place? Our vagueness about what we are doing encourages a certain incuriousness about whom we are doing it for. The impolite fiction about “no hostilities” might have been sustainable, in a public-relations sense, when the Libyan war was in a stalemate. Now, with armies on the move and cities falling, it has to be reckoned with.
