Firstly, Libyan rebels are not Al Quaeda. The are Libyan rebels, of a rather mixed composition, which means that they might have a few Al Quaeda operatives among themselves too... just like the US armed forces are likely to have, as if it matters, since it's pretty unavoidable! :P
Second, the Libyan rebels are certainly a promising candidate for states to establish diplomatic relations with, since the ports which happen to be located in areas controlled by rebels, do export a few barrels of oil... which sort of makes other states want to get cozy with them...
...and third: they are certainly a bit more legitimate on whatever scale (even my anarchist scale) than a dictator who has ruled 40 years.
Thus, what's the biggie?
And finally, a specific question to TheGer... do you have an ulterior political motive in depicting them as Al Quaeda? What benefit does a mis-characterization of this magnitude bring you? Where's the catch?
