I have my own reasons for supporting the use of atomic weapons against Japan. My dad (who passed away three weeks ago last Wednesday) served on a Navy LST and would have participated in the invasion of Japan. Judging from all I had read, there was a pretty good chance he would have not made it past his 22nd birthday if he had done so. The libs who whine about dropping the bomb can kiss my a$$. No Hiroshima and Nagasaki= No Big Red Clay. to quote Gene Hackman in "Crimson Tide" - "Drop that motherf---er, twice!"
Additionally, you can imagine the fallout that would have been involved if Marshall's tactical nuke plan had been used. Horrifying.
