And I must assume that you believe that one Arab life is worth more than dozens of Israeli lives. Which would also be in accord with the prevailing veiw held by the Arab and Palestinian governments.

This would be a valid belief on your part ONLY if the numbers were reversed and there were dozens of (Jewish) Israeli civilians killed for every non-Jewish civilian killed.

But they aren't, and so it isn't. It is simply a very ignorant attempt on your part to score a rhetorical point.
