the problem is that nukes effect does not end at the explotion, thats only a part of it,
alot of people would have to suffer from serious deadly deceases because of the radiations and even if they were lucky enough their children may not, they could be born in really wierd forms and have serious decieses whatsoever.
people are still dying because of this effect even today and those people are not counted in the number of casualities which can double or triple the number if they were to be counted.
