A yield of 5-15 is not a lot. if they drooped a bomb on Manhattan nothing i mean nothing will happen to people on Albany, buffalo, dc. And any country that does it just singed their end. Iran may do it but its because they are crazy but even 5 strategically placed nukes wont do squat America is a huge continent .
This in lamans is a maximum radius of about only 12 miles plus a maxi,um of another 10 radiation. Im not impressed plus in the epicenter its a painless death ..cancer is much more scary to me!
Iran has a death wish if it can think its crappy made bombs will wipe out the entire country , there is NO such weapon. This is not Star Trek The Next Generation.
Israel however is another story because its so small.
