"This would be a valid belief on your part ONLY if the numbers were reversed and there were dozens of (Jewish) Israeli civilians killed for every non-Jewish civilian killed."

Hardly. The Hezbollah use of area bombardment rockets against a civilian region is proof of direct targeting of civilians- YOU have provided no such proof of deliberate targeting of civilians not at or near military targets by the Israeli armed forces. Roads, munition depots, headquarters, and fuel depots are all legitimate military targets.
