ENCLOSURE II

You will all have seen the important statements which have been made by President Truman and by Mr. Stimson, the United States Secretary for War, about the atomic bomb. The problems of the release of energy by atomic fission have been solved and an atomic bomb has been dropped on Japan by the United States Air Force.

President Truman and Mr. Stimson have described in their statements the nature and vast implications of this new discovery. You will, however, expect to hear some account of the part which this country has played in the remarkable scientific advances which have now come to fruition. Before the change of Government Mr. Churchill had prepared the statement which follows and I am now issuing it in the form in which he wrote it.

It is now for Japan to realize in the glare of the first atomic bomb which has smitten her, what the consequences will be of an indefinite continuance of this terrible means of maintaining a rule of law in the world.

This revelation of the secrets of nature, long mercifully withheld from man, should arouse the most solemn reflections in the mind and conscience of every human being capable of comprehension. We must indeed pray that these awe-striking agencies will be made to conduce to peace among the nations, and that instead of wreaking measureless havoc upon the entire globe, they may become a perennial fountain of world prosperity.

What is this source?

The beginning of this document is an extract from a statement issued by the British Prime Minister Clement Attlee following the dropping of the Atomic Bomb on the Japanese cities of Hiroshima and Nagasaki in August 1945. What then follows is a statement which had been written by Winston Churchill prior to the change in government (and therefore prior to the dropping of the bombs).

Background to this source

There are two important points about this source. Firstly, although Nazi Germany had been defeated in May 1945, the war against her ally, Japan, continued. On 6 and 9 August 1945, the USA (with British support) dropped two atomic bombs on Japanese cities. Japan surrendered on 14 August. Secondly, the Labour Party in Britain had just won a General Election in July 1945, leading to a change in government. So although it was Clement Attlee who was Prime Minister in August 1945, it was Winston Churchill (his predecessor as Prime Minister) who had been privy to discussions with the USA about the dropping of the bombs on Japan.

It had been a shock to many people, including Churchill himself, when Churchill was not re-elected as Prime Minister in 1945. Attlee, the new Prime Minister, had served Churchill as Deputy Prime Minister in the wartime coalition government. Although he was not in power, Churchill retained a worldwide reputation as an international statesman.

Need help interpreting this source?

  • It’s clear from Attlee’s statement that Britain has been involved in some way in the development of the atomic bomb. He also describes the dropping of the bombs as a ‘remarkable scientific advance.’ Does it sound like the government supports the weapons?
  • Churchill says that Japan will realize – now that the bomb has been dropped on Japanese cities – that she has little choice but to surrender. Do you think he believes this is a good thing? Would this also apply to other countries who wage war?
  • Churchill says that the secrets of atomic warfare have been ‘long mercifully withheld from man’. ‘Mercifully’ means ‘thankfully’.
