People all over the world thought that Israel would finally use the opportunity at hand to destroy Hizbollah and finish Nasrallah. This didn't happen. In fact, the IDF did not even retrieve the captured IDF men or stop the Hizbollah rockets. Although Israel cleared out a lot of dead wood after this war, including their defense minister, their chief of staff and seven other generals, we still don't know why Israel did so poorly on ever level. The fact that they employed even more secret weapons then we knew about doesn't help- answer the question. That is, unless Israel is so infatuated with their high tech and intel advantage that they simply neglect the basics of war fighting.
