Dhameystir weedha soo socota: Qeybta saddexaad ee cilmi-baarista Hasegawa waa taariikhda caalamiga ah ee ku lug leh Midowga Soofiyeeti, Mareykanka, iyo Japan si loo soo afjaro Dagaalkii Baasifigga. Markii ay Maraykanku ay bambooyinkii atomiga ahaa ku tuureen Hiroshima iyo Nagasaki bishii August 1945, 1.6 milyan
Ciidamada Soviet-ka ayaa weerar lama filaan ah ku qaaday ciidamada Japan ee ku sugnaa Bariga Aasiya. Hasegawa wuxuu daabacay buug, "Racing the Enemy: Stalin, Truman, and the Surrender of Japan" (2005). Isaga oo ka soo horjeeda aragtida guud ee la aqbalay ee ah in qaraxyadii atomiga ee Hiroshima iyo Nagasaki ay ahaayeen qodobka ugu go'aaminta badan go'aanka Japan ee ku saabsan inay is dhiibto oo ay soo afjaraan Baasifigga, Hasegawa wuxuu soo jeediyay aragtida ah in soo galitaanka Midowga Soofiyeeti ee dagaalka, iyadoo la jabinayo Heshiiskii Dhexdhexaadnimada, ayaa door ka muhiimsan ka ciyaaray bambooyinkii atomiga ahaa go'aanka Japan ee ku saabsan inay is dhiibto. Aragtidaasi waxay ka soo horjeedaa dhaleeceyntii hore ee duqeynta, sida Gar Alperovitz, oo ku dooday in ujeedada aasaasiga ah ee Madaxweynaha Mareykanka Harry S. Truman ay ahayd soo bandhigida awoodda militariga Mareykanka si looga hortago himilooyinka hoggaamiyihii Soviet Joseph Stalin. Sida laga soo xigtay taariikhyahanka reer Australia Geoffrey Jukes, "Hasegawa wuxuu si cad u muujinayaa in ay ahayd ku dhawaaqista Soviet ee dagaalka, ee aysan aheyn bambooyinkii atomiga, ee ku qasbay Japan inay si shuruud la'aan ah isu dhiibaan". Aragtidiisa ayaa la dhaleeceeyay. Dooda ugu dheellitiran uguna firfircoon ee buuggan waxaa lagu bixiyaa doodda H-Diplo ee miiska wareega ah ee Gar Alperovitz, Michael Gordin, David Holloway, Richard Frank, iyo Baron Bernstein. James Maddox, oo ah Professor of History Emeritus oo ka tirsan Jaamacadda Pennsylvania State University, iyo qoraaga buugga "Weapons for Victory: The Hiroshima Decision Fifty Years Later", wuxuu ahaa mid ka mid ah kuwa ugu adag ee buugga dhaleeceeyay.
