This month marks the 70th anniversary of the atomic bombings of Hiroshima and Nagasaki.
The blasts combined killed anywhere between 129,000 and 246,000 people.
And while some credit them for ending World War II, the ethics of using those bombs has long been questioned.
The National Atomic Testing Museum is commemorating the bombings with a new exhibit.
