I was dismayed to read the responses to the Watertown Citizens’ article about the importance of commemorating the 75th anniversaries of the Hiroshima and Nagasaki A-bombings. These comments reflected ignorance of history and passion for vengeance. As we know, the refusal to learn from history means that it will be repeated, often in a disguised form. Most important to know is that the A-bombs initially killed approximately200,000 innocent children, women and men, with many more dying from cancer and other radiation diseases in the years that have followed. In time, it will be broadly understood that the Asia-Pacific theaters of WWII were the result of clashing empires: Japanese, U.S. and British.
