Question

it was to spare the japanese people from utter destruction that the ultimatum of july 26 was issued at potsdam. their leaders promptly rejected that ultimatum.
if they do not now accept our terms they may expect a rain of ruin from the air, the like of which has never been seen on this earth. behind this air attack will follow sea and land forces in such numbers and power as they have not yet seen and with the fighting skill of which they are already well aware.
—president harry truman, aug. 6, 1945
what is truman’s purpose in delivering this speech?
○ to apologize to japan for using an atomic bomb
○ to announce the terms of the potsdam declaration
○ to force japan to leave the philippines
○ to threaten japan with further attacks if it fails to surrender

Explanation:

• Analyze Option 1: Truman did not apologize; he was addressing Japan's rejection of the ultimatum, so this is incorrect.
• Analyze Option 2: The ultimatum was already issued at Potsdam, and the speech is about the consequence of rejecting it, not announcing the terms, so this is incorrect.
• Analyze Option 3: The speech is about Japan's response to the ultimatum and potential attacks, not about forcing Japan to leave the Philippines, so this is incorrect.
• Analyze Option 4: The speech states that if Japan does not accept the terms, they will face a "rain of ruin from the air" and subsequent sea and land forces, which is a threat of further attacks if they fail to surrender. This matches the content of the speech.

Answer:

D. to threaten Japan with further attacks if it fails to surrender
