If today Americans in the leisure of a long peace wonder whether our grandfathers were too hasty in their decision to resort to atomic weapons, they forget that many veterans of the Pacific wondered why they had to suffer through an Okinawa when the successful test at Alamogordo, New Mexico, on July 16 came just a few days after the island was declared secure. Surely the carnage on Okinawa could have been delayed till late summer to let such envisioned weapons convince the Japanese of the futility of prolonging the war.
