The effects aftermath on the cities was catastrophic, the explosion wiped out 90% of the Hiroshima, and instantaneously killed eighty thousand workers and civilians combined. more ended up dying later on from radiation exposure which was a slow agonizing death. Three days later, another atomic b-29 bomb hit Japan, but this time on a city called Nagasaki, killing around forty thousand people. The Japanese Emperor later announced to the people
of Japan, The United States and China, that they would withdraw and surrender from the war.
This attack displayed how America was in rage with Japan and wanted to get revenge for their lost comrades and damage made in the Pearl Harbor attack in Hawaii, after the attacks Japan had a lot of damages to rebuild, most of Americas boats and navy were lost to the pacific war, Japan had no allies and their islands were under naval blockade and their cities were going through multiple air assaults.
This clearly shoes that the United States was at an advantage in the war and Japan was on the verge of falling apart but the U.S still decided to use their bombs on the already economically challenged country to rebuild their cities, more casualties forced them to surrender the war which went against their "code of honor" creating a miserable ending to the war for the Japanese.
The affects of the mass destruction resulted in birth defects, body dysfunctions, cancer and traumatized civilians. In the process America had also inspired other countries to produce and manufacture nuclear weapons for war use, which made nine nations harbor these devastating weapons such as the United States, United kingdom, Russia , France, China, India, Pakistan, Israel and North Korea posses these weapons in their armory, approximately 16,300 nuclear weapons in total.
To wrap it up, I do not support the fact that the U.S dropped not one but two atomic bombs on high populated cities, mainly because it costed Japan a fortune to rebuild the cities and the bombs killed thousands of innocent people.
