@engineer,
I don't know that that's entirely true. All of the actors in the Bosnian and Kosovo atrocities seem to have believed that they were somehow immune. I can see that to a point with Milosevic, who probably believed that Serbia would not be attacked, and that the Serb people would never turn him over to an international tribunal. For Karadsic and the other Bosnian Serbs who were charged with war crimes, though, it was incredible hubris, or stupidity, or both. The atocities in Kosovo were just so far off the scale of what anyone else--Bosnians, Croatians or Kosovars--did to the Serbs, that it isn't hard to come down on the side of their victims. About 2000 victims were found in mass graves in Serbia itself, and at Srebrenica (sp?), there were about 8000 victims in that one incident--i doubt that all the other actors combined were guilty of 10,000 murders.
The Libyan situation is much different, though. This is not a case of attacking a despised ethnic or religious minority. Additionally, there is nowhere for Kadaffi to run to and hide, unless he gives up and flees the country. (Once again, i feel certain that Milosevic thought he was untouchable as long as he remained in Serbia.) Kadaffi is not that stupid. For all that he's a monster, he's a clever one. I'm not sure that he'll want to create a situation in which no nation will have him, and in which there will be nowhere for him to run to if he is driven from power. Of course, we both only speculate.
