If Hiroshima and Nagasaki happened on a yearly basis, it (the ~220,000 people) doesn't even pale in comparison to the 4.6 million people who die from fossil fuel burning.

Since I was born, 92 million peoeple have died from fossil fuel burning (likely more as it's gotten cleaner) and if the nuclear bombings happened every year only 4.4 million people would have died from 400 nuclear bombings.
