Did anyone
not see this ages ago? The Libyans have oil, and that's motivation enough

Anyway, it's probably just going to make things worse for Libyans in the short term. Let's hope the long term benefits to the people of Libya outweigh the short/mid term suffering.
It'd be really nice if the US could
stop going to war with everyone though, and just be happy with peace for once.
/edit
I don't think this is going to be as bad as Iraq, because the people are already in rebellion, and once the current Libyan government is gone, the violence will
hopefully die down pretty quickly.
