									 The ATOMIC BOMB &
   the END of WWII




TO BOMB OR NOT TO BOMB?
            RECAP…
1. Name the Allied strategy in Europe & the Pacific.

2. Name 2 battles in Europe

3. Name 4 islands we go to in the Pacific…can you
   get the right order? (hint: MGIO)

4. What type of warfare do the Japanese use?

5. What “lie” did the Japanese tell & what
   happened because of it?
    The Allies are worried about
         Invading Japan…
They’ve been “warned” not to invade

                        You invade us….
                      This happens to you!
           But…
the allies have something
  else up their sleeve…
  Manhattan Project:
“The best kept secret of War”

• 600,000 worked on it

• July ’45 they tested it in
  New Mexico
 – Flash visible from 180 miles away
 – More powerful than they thought
     To bomb or not to bomb?
Here’s what Truman had to decide…Do we,

1. Not drop the bomb…Invade Japan and lose an
   estimated 2 million allied troops & waste millions
   developing this bomb

2.    Drop other (non atomic) bombs on cities in
     Japan & blockade so they starve

3.     Drop the A bomb in the ocean to scare Japan
     into surrender (and the SU?)

4.    Drop the Atomic Bomb on civilian populations to
     make Japan surrender & save US/Allied lives
  Many Protested its use…
 Including the scientists who
           made it!
             BUT…
  Truman ordered it to be used

• Gave Japan one last chance…
    • “prompt & utter destruction”
    • Japan refused to surrender
