It makes the Hamas leadership visible and available. And if they keep on with the 'exterminate Israel' theme, the tendency to 'glorify' the fight of the Palestinians--who have been used as pawns for decades by both the Jewish State and many of the Arab countries that surround Israel--will be met with a somewhat colder reception that it has to date. Tom Clancy in a recent book (bloody awful, IMO) started it with what I think was a quotation (but that could be faulty memory on my part) that read something like, "If you intend to grab a tiger by the tail you'd better have a plan for dealing with its teeth." Hamas would be well advised to keep that in mind.
