The reason France, Italy and England are hell bent on bringing a quick and "positive" end to the uprising is beacause they know that if they let Gaddafi win, then when he starts the carckdowns all those 100,000's of refugees will end up on their doorstep, AGAIN! Just like with Iraq, Aghanistan, Pakistan, Egypt, Turkey, Yugoslavia, Libya, etc...
Anyway, why would the EU give a flying fornication about suicide bombers from Libya killing US military in Iraq? I mean it is quite clear, to anybody outside of the US, that the sole purpose of US military presence in Iraq is to protect (American) corporate oil interests. If the US really gives a crap about the servicemen and women in Iraq then all it has to do is withdraw them. It's quite simple really.
Anyway, if the EU did not offer air support to the rebels Gadaffi would have just leveled every city that did not support him, just bombed the crap out of them! Should we just stand aside and watch him do this?
Of course there are a variety of economic and geopolitical issues being played out on the sidelines, but...
With the eye of wisdom we discover a lot of anger in us, any amount of jealousy, resentment, ignorance, desire - mountains of emotion whose existence we would never have suspected in ourselves... We recognize that most of the faults we perceive in others are only the mirror of our own negativity, the reflection of our own disturbed feelings... At the same time, we relieve the world around us of the burden of our own negative judgements."
