Are they serious? Anyone who knows anything about Hizbullah (i.e. IDF/IAF) knows that the reason Hizbullah is so much much more successful militarily than Hamas and Islamic Jihad, for example, is precisely beacause THEY DON'T OPERATE OUT OF CIVILIAN CENTERS because of fear of collaborators. There are even political members of Hizbullah who will never encounter Hizbullah fighters because of that fear on the part of Hizbullah leadership. Of course the Israelis are going to say that Hizbullah was operating in Qana rather than saying "Yes, we killed lots of children." If leveling all of south lebanon is the only means for Israel to achieve its aims, then its aims are illigitemate and unachievable under international law.
