Supplying weapons is neither proof that these people are thugs, nor is it proof that the rebellion was not genuine.
Then you probably should educate yourself on his regime and its policy towards Libyans, both at home and abroad. The US's support of Libya is something along the lines of their support for Pakistan -- the enemy of my enemy is my friend. Gaddafi was not a popular figure in Western circles.
I have no "perception of behavior." My opinion on the rebellion is that it was genuine. Once NATO saw that momentum of the Arab Spring could potentially carry this rebellion all the way to Tripoli, they pounced on the opportunity to back the rebels. Gaddafi has been an unpopular figure in the West, mostly for his ties to terrorism, but also because of his brutal regime. NATO took the rebellion as an opportunity to displace him and install another democratic government. Whether that last bit comes to fruition remains to be seen.
Your failure here is to provide one iota of evidence that these men are "thugs." You cannot even define what you mean by the word, though you can tell me specifically what it doesn't mean. I don't see any evidence that the men who started this rebellion were hired by NATO and you have yet to provide this information.
Agreed. I can see three possible scenarios here. First, Obama and NATO discover evidence that Gaddafi is not living up to his Bush conversion and is indeed still sponsoring terrorism. Second, NATO's European members decide that other Gaddafi activities tip the balance from tolerable to intolerable. Third, Obama and/or NATO decided that the rebels were likely going to succeed and thus we might as well be on the winning team. Any of those and perhaps a dozen others might be the reason we jumped in - most likely it was some combination of things. Bush-bashing aside, Presidents usually see numerous reasons pro and con on any particular proposal, and have to decide whether the former beats the latter based on whose projections they most trust. They are not cape-wearing cartoon villeins out to kill people to enrich their friends or allies, nor do they make these decisions lightly.
And Presidents deserve a fair amount of latitude to make these decisions, as especially in foreign policy they cannot lay out all their cards on the table. This is true to some degree in everything - a President may well have to bail out a bank because his advisers tell him that other banks are borderline insolvent and a major loss of trust will take them down too, knowing he'll have to take his political lumps for doing so - but it's always true in foreign policy. This is doubly true in the Middle East, where leaders may well be telling their own people something quite different from what they tell our leaders. And in this case, it is highly unlikely the result will be worse than Gaddafi, either for the West or for the Libyan people. At the very least they'll have a shot at a free democracy, and while it may be Sharia-based, any free democracy will eventually be what the people are willing to accept.
