the classification of your enemy as less 'human' than yourselves - it certainly seems from the IDF's POV that 1 dead Israeli is worth 10 dead Lebanese.
You are again wrong. If this was the case Israel would not have entered all the hostile Lebanese villages in southern Lebanon with soldiers but would have bombed the villages to a pulp and then entered the village. The opposite is true. IDF first surrounds the village, obtains intelligence, uses air and artillery fire only upon identification of hostile forces and then enters the village with house to house searches. So I guess your perception of the IDF is wrong!
