People vaporized, bodies left shadows
People’s burned skin peeling in red strips
Buildings completely destroyed
Radiation poisoning led to future deaths
How did the U.S. occupation of Japan
impact its future?
For later – think about the righteous of
dropping the bomb?
Are civilians an appropriate target of war?
Right or Wrong?
• Historians still debate this today
• Sides are split

70,000 nuclear weapons in their collective
nuclear arsenals.

arsenals/abilities: U.S., U.K., France,

For the Dropping of the Bomb
President Truman
"Having found the bomb we
have used it. We have
used it against those who
attacked us without
warning at Pearl Harbor,
against those who have
starved and beaten and
executed American
prisoners of war, against
those who have
abandoned all pretense
of obeying international
laws of warfare. We have
used it in order to shorten
the agony of war, in order
to save the lives of
thousands and thousands
of young Americans.”
General Leslie Groves
“As to the present war,
there was a feeling
that no matter what
else might happen,
we now had the
means to insure its
speedy conclusion
and save thousands
of American lives.”
Secretary of War Stimson
"These two heavy blows
have fallen in quick
succession upon the
Japanese and there will
be quite a little space
before we intend to drop
another. During that time
I hope something may be
done in negotiating a
surrender. I have done
the best I could to
promote that in my talks
with the President and
with Byrnes and I think
they are both in full
sympathy with the aim."
Against the Dropping of the
Bomb
Albert Einstein
"I made one great
mistake in my
life…when I signed
the letter to President
Roosevelt
recommending that
atom bombs be
made; but there was
some justification the danger that the
Germans would make
them."
General Eisenhower
"During [Sec. of War Stimson’s]
recitation of the relevant facts, I had
been conscious of a feeling of
depression and so I voiced to him my
grave misgivings, first on the basis of
my belief that Japan was already
defeated and that dropping the bomb
was completely unnecessary, and
secondly because I thought that our
country should avoid shocking world
opinion by the use of a weapon whose
employment was, I thought, no longer
mandatory as a measure to save
American lives. It was my belief that
Japan was, at that very moment,
seeking some way to surrender with a
minimum loss of 'face'. The Secretary
was deeply perturbed by my
attitude..."
Debrief
Respond to each in one paragraph:
1. Was the decision to drop the bomb a
military necessity? If not, was it
justifiable for a reason besides military
necessity?
