I’ve been trying to articulate why the intervention in Libya against Qaddafi is a good thing. And why the reflexive rejection of it as an imperialist oil grab is just that: some kind of reflex, not thought through.
Luckily, Juan Cole  has expressed it much better than I could have, and on the basis of a much broader and deeper knowledge of the situation.
From his closing paragraph, after he’s laid out all the reasons why:
I would like to urge the Left to learn to chew gum and walk at the same time. It is possible to reason our way through, on a case-by-case basis, to an ethical … position that supports the ordinary folk in their travails in places like Libya.
