For nearly two decades, Yuki Miyamoto, a professor and second-generation Hiroshima hibakusha, or atomic bomb survivor, has tried to teach her students at an American university about the terrible toll nuclear weapons take.

Perplexed by the justifications given in the United States for dropping the bombs on Hiroshima and Nagasaki in August 1945, she traveled to the U.S. to pursue studies in ethics where her work now mainly focuses on nuclear discourse at DePaul University in Chicago.

Today, she says many still believe what she considers a "myth" that the A-bomb helped save many American lives by hastening the end of World War II and the majority show little interest in nuclear issues.
