Question

what was a concern of some scientists after the manhattan project?
○ with germany defeated, they did not think that japan would be a threat.
○ they did not think that truman was knowledgeable enough about atomic options.
○ with germany defeated, they did not think there was a need for an atomic weapon.
○ they did not think the us had adequate staffing to continue development of weapons.

Explanation:

The Manhattan Project developed the first atomic bombs, primarily initially targeted at Nazi Germany. Once Germany surrendered in May 1945, many scientists involved argued that the original justification for the weapon (defeating Germany) was gone, and they questioned the need to use or further develop it against Japan without exploring alternatives. The other options do not align with the core concerns of these scientists post-Germany's defeat.

Answer:

With Germany defeated, they did not think there was a need for an atomic weapon.
