Lets Get Real:
Israel has to LOOK at the big picture, the main threat to Israel is Iran, a nuclear armed Iran at that, Gaza is a bad case of gout, a pain, while Iran could be a heart attack. The Oval might think it would be a good idea for Israel to attack Gaza, if they are at War on that front or with Syria they cant be attacking Iran. The Oval is that cynical folks. Thus Israel should stay its hand, deal with Iran first, IRAN is the major threat, any border WARS are small fry, and only help IRAN with time to develop the BOMB. Lets hope there a clever and cooler heads in Israel, a ground attack on Gaza would be a military and political mistake at present.
