I don't know if its been covered here or not, but it's pretty clear that Israel is acting within the articles of the Geneva Convention and Rules of War, in attacking military objectives that are situated among human shields, so long as certain requirements are met, such as giving civilians advance notice. See Part 2, in link below
Rules of War There is a concept floated recently by Attorney Alan Derschowitz, with whom I agree on almost nothing, concerning differing degrees of "civilianness" - a totally innocent person on one extreame, a person with some level of complicity in the middle, and on the other extreme, a person who is non-military, but nevertheless is complicit in hostile acts against the enemy. I think it fits the situation face by Israel very well.
Israel will be the first to do a nuclear strike, and there will be mulitiple targets. Most of the world wouldn't mind if Israel goes down, so long as it goes down quietly, without using nukes. Aint gonna happen. So Israel gets backed up against the wall, and the world refuses to help. It is easy to predict what WILL happen.
Its ironic that the Europeans and others are taking pot shots at Israel, but none of lthem are willilng to step up to the plate to contribute to a buffer force in Lebenon, USA and Britain included, though for understandable reasons.
