Martyr Math 101

A frequent claim by the anti-Israel crowd is that the targeted assassinations do not serve any useful purpose since "for every Hamas leader killed, hundreds of young Palestinians are recruited to the cause".

But now, after Israel wiped out the second Hamas leader within a month, they have decided to keep the identity of the new head a secret:

After Israel's assassination of two of its leaders in less than a month, Hamas decided to keep the identity of its new supremo in the Palestinian territories a secret, in line with a call from Meshaal

Perhaps its my high-quality grade 8 education speaking here, but that doesn't make mathematical sense. If every targeted assassination only helps the Hamas cause, why would they be hiding the identity of their new leader?

Maybe they use alternative math over there in the mideast...
