We seem to not really have a good answer to the missiles from Hamas. Our main answer seems to be to try to pound them from the air as hard as possible (taking into consideration many different factors) and expecting them to stop just in order to avoid our harsh response. We also try to destroy as many rocket caches as possible.. but that will just hurt their capabilities and not really take them away. So we don't really have answer other than hopefully they will one day decide it is just not worth it.

Professor Yisrael (Robert) Aumann, on the other hand, says he is working on a real response, a real answer. And it is one that nobody will really be able to legitimately complain about.

Aumann says, in an interview in NRG (via INN, which is where I saw it):

Nobel laureate Professor Yisrael (Robert) Aumann has an idea that could turn the tables on Hamas's rocket terror against Israel.
In a recent lecture, he described his vision for a fully automatic system that would fire a rocket back at Gaza immediately, whenever Gaza terrorists fired a missile at Israel. Presumably, these missiles would be randomly or automatically aimed in a way that would inflict civilian casualties on the Arab side, just as Hamas seeks to cause civilian casualties on the Israeli side.
Asked about the idea in an interview by NRG, Aumann said: “I'm working on it. The goal is truly that the system will be without any human involvement, no human control. This is very important, because if there is control, they will tell us that we are criminals and murderers and cruel.”
However, he explained, if there is no control of the system on the Israeli side, the responsibility for civilian deaths caused on the Arab side falls on the people who fired the missiles that set off the Israeli system. Prof. Aumann compared this to a situation in which the Arabs “take their women and children and force them to walk through a dangerous minefield.”
Would the system keep the world from blaming Israel? Prof. Aumann says that there will probably be criticism in any case, “but at least then we will feel more at ease with ourselves. If the response fire is automatic, the [Israeli] threat is convincing: when Hamas fires a rocket at Israel, it also fires a missile at Gaza.”

Will it work? An automated system that fires a missile back every time an incoming missile is detected, and it would in turn target a civilian population? I am not sure why he thinks automating it will remove the possibility of criticism, or even just put us more at ease. It would still be our system, that we programmed, that is shooting at civilians.

True, it means Hamas is directly triggering our missile as well by shooting their own, but it still would be our system shooting at Gazan civilians. It does not seem to me to solve the moral dilemma or to be the answer that will prevent international criticism.

Perhaps something even less controlled by us is a better answer. Something like a rubber wall or an iron trampoline, of sorts, where the missile shot by Hamas is turned around somehow and redirected into Gaza. The missile would sort of hit the trampoline or rubber wall and bounce back toward Gaza. Then they are the only ones shooting the missiles and it would be their missiles falling on civilians in Gaza.
