Saying "you cannot force a civil war" is a bit like saying "you cannot trigger an avalanche".

"A population who are happy with their lot" would be an excellent thing to have in any country. But I'd suggest sadly there are relatively few countries where there is not a significant part of the population at any time that is not that happy with its lot.

Resolution 1973 was an emergency response to fears of an imminent massacre of civilians. Whether such a massacre was in fact imminent is something about which there will no doubt be disputes by historians in the future, but there is a reasonable case for arguing that it was, and that an immediate no fly zone with military action to halt the advance of government troops into Benghazi was required.

But that is a separate matter from continuing air raids to bring about regime change in Tripoli, and refusing to make any efforts to implement the UN demand for "an immediate ceasefire" which was also contained in Resolution 1973.
