Nuking the Gaza strip (unless they used neutron bombs of limited yield, and aimed carefully) would affect Israel too.
True regarding nukes on Gaza. I was thinking of other targets, though the world would see such acts as irresponsible.
Limited yield bombs would be useful only on specific, known targets in Gaza, but I think Israel has plenty of conventional weaponry to deal with that. Reckon they have a few bunker busters ready to unleash on those particularly pesky underground sites.
