. On July 27, 1945, he observed that unconditional surrender applied only to the military and not to the government or the people, and he pleaded that it should be understood that the careful language of Potsdam appeared "to have occasioned a great deal of thought" on the part of the signatory governments—"they seem to have taken pains to save face for us on various points." Nevertheless, Japan rejected the Potsdam Declaration, and soon thereafter atomic bombs fell on
