So your saying he should just abbandon his country because they are killing a lot of people in an attempt to make their own citizens safer. In Israel everyone fights (not sure about the women...) which seems like a good idea being that there's so much hate ready to come down on them at any given time. That you would even suggest these things to a member of the Israeli military is quite amazing to me. Civillians are the ones who question their governments not soldiers, and while someone is a soldier they have a duty to follow orders and defend their country. All I hope is that Death Boo Z stays safe.
As I see it. Israel is doing a lot (relatively) of collateral damage and this is very unfortunate for the Lebanese, but from Israels perspective doing nothing will likely lead to more attacks on Israel. Any reasonable leader would attempt to take the fight to the enemy rather than accept more deaths among his/her own people. If it comes down to Lebanese civillians and Israeli civillians and someone is going to die, [This Is Where An Obvious, 'No one has to die' Counter-Argument Goes!!!!!!!] the Isrealis will protect their own. Sure it's not 'right' by most standards to kill in the hope that others won't be killed if you do, but if nations only did what was right by some arbitrary, and regardless of how hard you try 'right' will always be arbitrary, definition then anyone who wasn't willing to follow the 'right' path could run all over them.
And as to the UN, is the UN going to protect Israel's citizen's? I doubt it, and from Israel's behavior they probably doubt it as well. The UN lacks the punch that goes along with it's supposed authority, it can give and take favours but it doesn't have the third leg of authority, the ability to inflict direct damage. The reason countries like the US and Israel ignore it so much is because it most closely represents the type of idealistic 'right thing only' organization of any world body. The UN will always seek to avoid causing suffering of any kind, even when there is no other option to induce complience. It is interesting how well the UN and countries match with parents and children.
Some parents are like the UN and refuse to inflict harm to discipline their children Instead they negotiate with the children, taking away privilages or offering incentives in the hope of bartering for a desired behavior from them. I have seen many good people who grew up never having a hand raised to them in punishment, and they are respectful and obedient. I have also seen children who were beaten for anything and everything who turned out to be terrible, disrespectful, and rebelious wastes of material. In addition to the ability of the one weilding the authority, the children themselves have something to do with how they turn out, just as the people/leaders of a country have something to do with how that country will respond to pressures.
Some countries, just like some children, can be brought into line with nothing but sanctions or incentives. Others will do whatever suits them no matter what you offer them or threaten them with. A notable thing is that the countries that come to mind as rebellious are generally fighting amoungst each other. The US and, to a lesser extent, Israel, share their disrespect for the 'rules' with countries like Iran, the old Iraq, and North Korea. The most likely reason being that these countries have strong ideological goals on an international stage and will to see those goals fulfilled to the best of their abilities. NOTE: When I reference a county I'm talking about it's government, not nessecarily it's populace.
And what is a 'just' war? When is it just to drop a 500lb bomb on something that's not yours. Even I don't think it's 'just' to attack someone else, even if you've been attacked. However I think you damn well better attack anyone who attacks you, and teach them a lesson lest they attempt to hurt you again. Justice and Righteousness have no place on a battlefield. When no one wants anyone dead anymore (or isn't willing to follow through on their desire), then people should start talking about justice, until then it's about saving your own ass any way you can.
