For what it's worth, I think I agree with our intervening in Libya. Certainly the reasons for it make a lot more sense to me than our invading Iraq did, even back before we learned all we have about Bush & Co's lies.
Yes, we have our own problems. But I think I agree with this intervention because, when I think of my country sending people to risk their lives in the name of all of us...this is what I want them to be doing it for.
One of the many faults with the Iraq war, as I have come to see i,t is that we couldn't spark a rebellion at the point of a gun. In the case of Libya, the rebellion has clearly already been sparked...and not by us.
What we're doing, and fortunately we're not alone, is going in to stop a rebellion from being violently quashed. That's what we should be doing, I think (this puts me in a minority, BTW). I look at it this way:
You're walking along and across the street you see a man and woman fighting outside a cafe. From what you can hear, she's leaving him. She gets up from the table and starts to walk away. Whereupon, he says "Oh no you don't," grabs her from behind and smashes her head onto the sidewalk.
Do you go over and try to stop it? I sure hope I would.
