If you don't want it, and you don't want a museum to have it, the other option is to sell it. Someone would be thrilled to have this piece of history, associated with the bomb.
As far as the strange "not wanting to be associated with it" comments, I concur it's just an inanimate object. But the Manhattan Project was America's largest industrial project ever accomplished. It's goal was to build the bomb before the Nazis did, because as we know with the German Vengeance weapons, the V-1 and V-2 (made by slave labor who were worked to death) WERE being used daily against civilians. If the Nazis got the bomb, they would have used it to decimate Europe. When we won the European war conventionally, the bomb was still very useful.
We didn't start the war, Japan and Europe did. By dropping the Bomb, all service members at the time had their lives spared. It was estimated that another 250,000 to half million Allies would have died trying to assault the home islands of Japan like we did at Iwo Jima and Okinawa. There....every Japanese soldier and thousands of civilians fought to the death, or committed suicide. So not only did the Atomic bomb save as many Americans as we had already lost in WWII, it saved millions of Japanese who would NOT have surrendered.
The camera is a piece of important history on how America saved the world from Japanese raping and beheading in China and the Pacific, and and the Holocaust. Don't forget why we were there, we didn't start the war. We ended it.
