Seriously.
One of the big problems with the Lebanon situation, as I understand it, is that the central government is too weak to prevent [link|http://en.wikipedia.org/wiki/Hizbollah|Hezbollah] from doing pretty-much whatever it (and Syria and Iran, if you believe the rumors) want. How will making war on a government and a country defeat a terrorist organization that the government can't control? Should Israel simply annex Lebanon or set up a [link|http://en.wikipedia.org/wiki/Protectorate|protectorate] or something?
(This is different from Afghanistan in that only 3 countries recognized the Taliban government as being legitimate, while Lebanon was recognized as sovereign; etc.)
Hezbollah isn't going to permanently stop doing what it's doing as a result of Israel's actions. (Israel can't kill all of Hezbollah without killing many civilians as well; and even if it could it would just strengthen Hezbollah's ideology.) The government of Lebanon is too weak to get it to stop, either. AFAICS, the only way this can end is for Israel to either 1) declare victory and go home; 2) repeat the [link|http://en.wikipedia.org/wiki/1982_Lebanon_War|1982 fiasco] and stay another ~ 20 years; 3) have some sort of wink-and-nod agreement with Hezbollah to release some of the prisoners, as they did in the [link|http://www.jewishvirtuallibrary.org/jsource/Society_&_Culture/prisonerswap012904.html|recent past]. Option 1 is what China chose in its [link|http://web.mit.edu/cascon/cases/case_chv.html|Teach Vietnam a Lesson] battles in 1979. Option 2 has been shown to be a long-term failure. Option 3 doesn't change the facts on the ground, but it costs much less in lives and destruction. Israel isn't going to get Hezbollah to say Uncle, and destroying Lebanon isn't going to help. The quicker it chooses option 3 (or 1) the better off everyone will be.
Ideally, the UN would send in an overwhelming force to stabilize the country and disarm Hezbollah to end these provocations. But that's not going to happen and everyone making speeches demanding "unconditional" actions on various things at the UN knows that.
My $0.02.
