Libya

So it's becoming more and more blatantly obvious that what we're really after here is regime change - William Hague (Foreign Secretary) is now on record as saying that unmanned drone aircraft could be used in an attempt to assassinate Gaddafi.  But what then?  As far as I am aware, there is no credible cohesive opposition or opposition leader, so Gaddafi goes and....?  I would like to think that someone has thought this through, but I have to say that I have my doubts.  Is this a case, at least in the short term, of  "better the devil you know"?
