Whatever the officials predict, the catastrophic outcome of a  nuclear attack will be multifold what they predict given the true unpreparedness and Murphy's law.  Puerto Rico, is an example of what we will face due to grossly inadequate response from the federal government, not only because of Trump ignoring Hawaii in retaliation, but because life-saving resources will not be coming our way, being drawn off to other areas that may be attacked or transport infrastructure damaged/destroyed.  Can you imagine when food and water are unavailable and people are at each others throats, among other total chaos?
