I am no miltary strategist, but it has always seemed to me that Israel's policy of putting up with a certain number of Hamas rockets, then retaliating by a single massive air attack on Gaza, was a mistake in that in this way it attracted the maximum of obloquy on itself.
Far better to have made a public offer to Hamas: five rockets incoming Monday, you will get five 155mm howitzer rounds back into Gaza Tuesday. Two incoming Tuesday, two rounds back Wednesday, Nil incoming Wednesday, nil back Thursday.....and so on.
Besides fulfilling the Biblical injunction of "An eye for an eye, and a tooth for a tooth", it would be a perfect example of a "measured response" and put Hamas on the back foot.
But then, what do I know ?
