alt Hacker NewsI didn't want to digress too much on that sidebar but the split on Nagasaki was mostly centered around the number of days between Hiroshima and Nagasaki. I think nearly everyone would have agreed the second bomb was probably justified had it been dropped later. Many felt that given more time the Japanese side might have changed their minds without the second bomb.
Let's minimise the digression, I'll move on happily enough ..
I'll note that it appears as if the events were framed to your class as two events predestined to have an excessive impact that deserved pause and consideration rather than as (in the context of contemporary events) two orthogonal weapon designs being field tested and squeezed into an already ongoing, months in the execution, campaign of systematic destruction of urban areas one after the other.
Eg: Was it stressed that had the Nagasaki bomb not been dropped the city would still have been destroyed to the same degree via heavy explosives and incendiaries?
