I would think this was the best way to achieve it with the very minimum casualties; as pointed out earlier, hezbollah themselves were only estimating civilian fatalities at a few hundred whereas independent authorities figured it was probably about 150 (this was a day or so ago, I haven't checked again today). Of course, it's hideous if even 150 civilians have been killed, but I would place the blame for that squarely at the feet of hezbollah. I actually find it really unfathomable how anyone else could be to blame tbh? They're the ones who sited their bases in residential areas after all - should we just allow terrorists to carry on murdering people at will if they have the foresight to set up shop in an apartment complex? Israel did warn people to leave ahead of time - and they did it after the pager attack so people knew they were serious. I think it's an extraordinary achievement and I can't imagine a way he could have been killed with any less harm to civilians. Can you? So the option would seem to be for Israel (and the wider world) to let him carry on murdering and essentially admit surrender to terrorism, or risk the death of some innocent people. Considering the number of innocent people who had been and continued to be at significant risk from the terrorists, I personally feel it was the right call. So it seems do very many who were living under his regime.
There will certainly be many angry little men who are hell-bent on revenge, but what's the answer then - just let the terrorists win for fear of creating new terrorists? The hope is that Israel have done so much damage that these wannabe avengers don't get a chance. It's a real shame hezbollah are continuing their unprovoked attack against Israel - and continuing to harm Israeli citizens. I find it very difficult to understand how on earth people can conclude they are not entirely to blame for every single death, be it Israeli or Lebanese.
Agree about Netanyahu though, I will be extremely surprised if he doesn't end up being found guilty of war crimes. Though - and I may be being far too generous - he might feel it worth it if he actually succeeds in significantly diminishing the threat to Israel.
