Capitalizing on critique: UN intervention as political tool

Watching live the vote in the security council was certainly a thrilling experience. There's a lot to be said here,and it was pointed out that the situation and the result was open as the council proceeded to vote; the five abstainees had different reasons for not entering into the vote - and most importantly - the two remaining veto powers also abstained. This was certainly a historic vote, and it served to reaffirm the UN security council as the world's top decision maker.
In the days to follow, the queue of people and groups wanting to critisize this grew longer and longer; and certainly when the attacks commenced. The leader of the Arab League remarked that "This was not what we voted for". It is always problematic to appear divided after a campaign has started, and it very often makes the game easy for the opponent. The question of the no-fly zone was controversial, because the US argued that such a thing would also have to include other operations than just some jets flying around in a circle above Libya. I felt that the critique of the Arab League was pretty near unreasonable, as only Qatar and maybe UAE were planning on supplying planes for the operation. The risk of being shot down would be too great if the anti-air-missile systems were not taken out, and why should only the western powers run this risk? The price tag on a jet is in the millions, not to speak of the potential loss of life. So quite frankly I'm a little provoked by all these loud critics of this resolution and the voting, because they never seem to come up with any alternatives. This leads me to suspect them of thinking about their own political standing when making critical remarks to the resolution and the intervention. How would it be possible to see eye to eye with the survivors of Gaddafi's brutalizing and hide behind the eternal excuse of internal affairs? I also think that the strong critisism regarding Libya's oil is exaggerated. Libya is not a producer of oil of a size that would totally ruin world economics.
