I'm with you Dov. )sorry, no hebrew here abroad)

Jericho first reminds me of the doomsday device in Strangelove. The thing is, it's not feasable unless it can be fully automatic. The whole idea of severing the human chain of responsibility for the retaliation - or to be mroe accurate, to deflect the responsibility onto the other side by making the process as automatic as possible - only works as long as the process Is actually automatic. As long as there is a soldier that has to carry out the order to retaliate by hitting civilians, even if it entails nothing more than clicking a button, it will be easy to hold him morally responsible for the consequences of the retaliation.
It's a cute idea, but probably not feasible.

Of course, the whole idea of automatic processes, which are of course intentional and planned, taking or transferring moral responsibility from their designers and operators, is just a moral intuition pump. This policy can have no sound moral justification.
That's not to say that I'm opposed to it - just that it will be impossible to reconcile it with morality (or prominent moral theories at least).
