This is a fascinating review, and it's great to hear a Japanese perspective. However, I personally disagree with you here. I think for a start, to suddenly cut to Japan when the bombings took place would have been both artistically wrong and patronisingly tokenistic. Leaving that aside, I think Oppenheimer's crushing, hallucinatory guilt, and the fact that the film does discuss victims (both immediate and afterwards, with radiation poisoning and so forth), rather refutes the idea that the film has no respect or sympathy for the Japanese.

All that said, to reiterate, this is an interesting and important perspective on the film. :)
