Let us start with the aftermath effect of war on Hiroshima and Nagasaki. On August, 1945, during WW2, a U.S bomber plane dropped an atomic bomb called 'Little Boy', over the Japanese city of Hiroshima. The explosion immediately killed an estimated 80,000 people. Three days later, a second bomb (Fat Man) was dropped over the city of Nagasaki, killing immediately an estimated 40,000 people. This acts forced the Japanese Government into surrender and as well leading to the end of WW2. 

But even with the end of WW2, the consequences of those bombs were just starting.

Through the next two to four months, the effects of the atomic bombings killed between 90,000 and 146,000 people in Hiroshima and 39,000 and 80,000 people in Nagasaki. For months afterward, several people continued to die from the effects of burns, radiation sickness, and injuries, coupled with illness and malnutrition. Painfully, most of the dead were civilians.

More so, the effect of the atomic bomb affect the genetic of the survivals. As a result many of them gave birth to critically deformed children: co-joined twins, legless or armless children, one eyed children and many more unimaginable conditions.
