The we refered to is the "west" the group of nations that have been deemed to be the cafeteria monitors of the world. Fuji's idea that Nato etc should " do something " is all well and good except for a couple of things.
1) Most of the western European nations have large Muslim populations that have the possibility of going nuts if the west invades a Muslim country see Sapin and he train bombing following Afghanistan , that is a major issue for them they do not want to inflame their own security concerns.
2) The US is already in an couple of wars , the current president is less than happy about it but he can not risk the publicity of a) withdrawing enough troops from one of the other zones to deal with this b) activating more troops could result in mutinies oin the ground in the states. The troops are tired , the budget is insane and his personal popularity can not take much more and stay in positive numbers , positive as in above zero. The political machinery will not allow him to damage their power retention policies..
That leaves the eastern european nato members most of which have muslim populations and are iffy from a military point of view.
U.N.
China just removed 30 odd thousand of its citizens from Libya, all those planes went in full and came out with people on them what went in is a question, although the fact that the planes were allowed to land and remove people with no fuss no muss and no notice until after the fact hints at an understanding of some sort. I expect the SC will veto any UN involvment.
Russia, a large question, they could probably do the no fly zone. the question is where would they base the aircraft. I don't see nato mebers supplying support, which leaves arab league countries , they will not want to be seen as supporting the no fly zone for the same reason they are not willing to do it themselves, they want to be able to blame somebody else if it goes sideways or if Gahdaffi stays i9n power ( which at this point seems likely)
So who does provide the bodies and machinery to assist rebels against their legitimate government. Knowing that it would set a precedent for future problems
