The US obviously doesn’t like Qaddafi (except when he’s convenient, like assisting in our extraordinary renditions).
So it’s one thing for Yemen to kill its own people, but another for Libya.
One thing for Bahrain to invite in Saudis and other foreign troops to squash a rebellion, but if Qaddafi does it it’s a sign that he’s an animal.
Egypt required a smooth transition and maintaining a bit of the old guard – Libya needs a clean start.
While I appreciate in principle defending people who are protesting their corrupt governments, it’d be nice if we managed some teensy bit of consistency across the region in doing so. Otherwise, our hypocrisy and particular bias is just a tad too obvious.
