As dystopian as it sounds, it's all politics and oil IMO. Obama's trying to make this his Kosovo to give him that much more to crow about during reelection (in addition to "making critical healthcare reforms" and "expanding gun rights"). I've called the man a bureaucrat who feeds on idealism before and I see no reason to abandon that line. I'd be overjoyed if there was a legitimate reason for us to be in Libya, but at this point we've already gone way past the UN mandate with no sign of stopping.
Guess I'll be proven right or wrong over the coming weeks. If Obama invades and gets us embroiled it'll be seen as his Iraq, and he knows it. If we do commit significant numbers of ground forces (beyond SF strike teams and escorts for humanitarian aid) then I'll admittedly have no idea what he's doing.
He argued about how the civil war could destabilize the region, but fact is Gaddaffi was kicking as and taking names up to the moment we started to take out his armor. Now he's kicking slightly less ass. If we had just let him be he'd have slaughtered the rebels and, despite the humanitarian atrocities, the region would still be as stable as it ever was out of fear and lack of capability.
Or maybe the humanitarian angle is the reason and Obama's just got some idealistic Neocon-ish interventionist tendencies?
Maybe he's trying to earn his nobel peace prize?
No way to know for now, just got to wait and see I guess.
