Former deputy IDF chief of staff Maj.-Gen. (res.) Dan Harel said on Tuesday at the Herzliya Conference that he did not think that the IDF had hit Hamas hard enough during Operation Pillar of Defense.
Harel's remarks were made during a panel discussing Israel's right of self-defense, and the strategic, moral and legal limits on that right.
Harel qualified his remarks slightly, saying that no final conclusions could be made about the effectiveness of IDF operation during Pillar of Defense until more time had passed.
But he supported his statement, noting that already, only a couple of months after the November hostilities between Israel and Hamas, a grad rocket was recently fired into Israel.
He said that, Operation Cast Lead in 2008-2009, in contrast, created a longer period of deterrence, because Israel had acted against Hamas with far less restraint.
