I'm more concerned over whether Israel's response will (a) stop Hamas from firing these rockets, and/or (b) further Israel's long-term security.

The results of previous Israeli military strikes into Palestinian territory suggest that (a) is generally not true, at least outside the very short term. Israeli politics suggests that no one has any clue whether anything Israel is doing will achieve or harm (b).

I think Israel should consider why international opinion seems to be swinging against it, and take steps to counter that swing, in addition to or instead of military actions like this.
