Not sure why my post from last night isn't here.
1&3) The US government is only damned if it does. The correct pattern for undertaking a just war is outlined in D&C 98 as referenced by another poster. This one doesn't even come close. Perhaps the Libyan rebel army has a just cause, again I am uncertain. If you feel there is compelling evidence that the Libyan rebels are undertaking a just war, by all means join them. But do not force others to do the same. You ask what I mean by mentioning force. I had some idea that you were in the military considering the silly jargon you previously used. As such you are part of a government that compels the conscription of my property to pay for an unjust war. Such compulsion is immoral and unbecoming one who has access to a greater knowledge. The fact that the same government forces you to pay for things you find objectionable does not make your cause any more just.
The most ardent anti-war and anti-military folks I know are ex-military, including many of the founders of this USA. Many of those were conscripted and forced to fight as slaves, but other volunteered. They all came to the realization of what war and the military represent through studying inspired political philosophy rather than international relations -- by studying how things should be rather than how things are.
2) Yes, if you notice Egypt lies just to the east and they currently have a large communist party. Hopefully they won't come to power in Egypt or Libya, but the point is no one has any idea whether the cabal that comes to power, in the event of the defeat of the Gadaffi, will be any better than the current regime.
4) The principle is the same, when your allies make unjust decisions you do not support them in those decisions. No matter how deep your "strategic relationship" with them is. Even if they are family. I'm not saying you abandon them but you most certainly do not aid them as they commit immoral acts. If France tried to retake Algeria, the Belgians tried to take the Congo, the Italians Ethiopia or the Turks attacked Armenia and the US government aided them, it would be just as reprehensible as what it is currently doing.
5) On a practical note you think Gaddafi is more or less likely to fire missiles across the Mediterranean after the bombing of Tripoli?
Finally, I think most people who join the military do so for honorable reasons. They believe they are are fighting to preserve freedom. Unfortunately the nature of the state is opposite the ideals of freedom, so they end up fighting against those ideals they hold dear. We idolize the state and the military in public schooling to such an extent that anyone who speaks against the military is portrayed as a traitor. That is why I recommend people read what the founders of this country thought about the military. If you are really interested, I'd suggest the Federalist (
http://www.thisnation.com/library/books/federalist/index.html) and Anti-federalist papers (
http://www.thisnation.com/library/antifederalist/index.html) (A couple of those dealing with the military are F24 (and 25-29) and F67 and AF24-25 and AF74).
