dear r/copypasta, i come to you at a time of great need. my (45M) teacher is asking me (7F) to complete my history assignment, regarding that of the hiroshima (12M) and nagasaki (13F) atomic bombings. this is a complex process and i am searching for any anime that may provide as a source, especially the anime it was originally from. my cringe (45M) teacher said that the bombings of these 2 cities are not from any anime, however i disagree as these cities both lie within the country of the japan.

please, any help regarding finding the source of this iconic anime scene would be highly appreciated.
