Uri Avnery: Israel keeps changing the "aim" of the attack on Gaza, so there is always a reason to keep attacking.

To keep it going, the US has just sold Israel more ammunition.

The latest "war aim" is to destroy Hamas tunnels, which Israel claims are meant to attack Israeli civilians. Never mind the fact that they have only been used to attack soldiers.

It's not clear the Iron Dome rockets are effective at destroying Hamas missiles (which seem to pose little danger in any case), but they are great for making loud explosions that get Israelis scared.

Israeli civilians have talked themselves into a frenzy of fear based on a danger that is tiny. That frenzy is, in objective terms, no justification for them to inflict great harm on civilians in Gaza.

The casualties (killed and wounded) in Gaza, around 10,000 people, amount to half a percent of the population of Gaza (1.8 million). If 30,000 Israelis were casualties of Hamas attacks, Israelis would face the same level of danger as Gazans, and I'd agree they had a valid reason to be frightened.
