Considering the Obastard administration's repeated attempts to isolate and polarize Israel, I think you're correct that these are supposed to be seen as to be used on Israel, not to protect Israel, presumably to attack the hardened bunkers in which Israel maintains its own nuclear arsenal, as well as the bunkers that would be used to protect Israel's leadership in the event of an attack.
Obastard probably doesn't have the cojones to actually use them against Israel (although I am sure that Rahm Emanuel does), but I am quite sure that they want to convey to Israel that they can be reached no matter what defenses they have, if they don't roll over and voluntarily walk into the gas ovens of right-of-return that the Obastard administration has prepared for Israel.
