Nuclear terrorism in New York City thus, would unleash immense devastation. If the bomb similar to “Little Boy” the bomb that hit Hiroshima were to drop in Manhattan, 99% of the energy would be released within a 200 meters radius and next 1% up to 340 meters adjacent the epicenter would include severely damaged buildings. Within the first few hours of the graduations the lives of tens of thousands would be extinct. After the blast, the blaze would trigger fires all over the place, while the radioactive isotopes would pollute the area and pose a danger to the people and emergency crews moving across the terrain.Contemporary nuclear weapons like the Russia’s RS-28 Sarmat or ‘‘Satan 2’’ are even more dangerous. With the capacity to bear several warheads, this missile was capable of causing much more devastation any “Little Boy”. The risult of explosion of 15-megatons would be fireball of 4 kilometer in diameter and all the objects within this zone will be burned completely. This blast required an area of destruction that would encompass most of the New York metropolitan area; structures would collapse in the affected expansive area due to the blast wave and the thermal radiation would burn most parts of the New York metropolitan area up to 34 kilometers away.

The consequences of such an attack would be felt far and near and huge sections of the city would be uninhabitable. It would be a disaster where incident management would hardly make any headway and the surviving occupants would have far reaching psychological effects. An explosive nuclear attack in New York is going to destroy not only the city, but also bring war to the whole planet which will be catastrophic, and cause millions of deaths.
