Israel should be responding with napalm and willie pete .
Forget the touchy feelie concern for collateral damage ; make it so costly that no one would ever consider attacking them again . Announce their nuclear targeting list , and state that they are presently ready to launch , and will launch if Iran does not replace it’s entire regime by the end of the week . That should be Bibi’s real red line
Something to publicly humiliate these rabid dogs. Having their “Forward” plan knocked backward tends to do that.
