Hitting just "Israel" would typically mean "hitting dirt", hence no need for interception unless the warhead is maneuvering one.What comes to the later remark: whatever:D
I dont think Israel would know from miles off where the missiles would land, if they see a big missile like a shahab on their radar, they will intercept, i dont think they have the technology that tells them "hold on no need to intercept, that ones going no where". I dont know, do they?
That tech was already in limited use in 1991 when Iraqi scuds were being intercepted by Patriots with varying levels of success. You know, those missiles... are ballistic missiles. The last advancements in this field are already at tactical level (Iron Dome and other similar systems).
