Changes

After [[World War II]], nuclear weapon research continued with the development of the [[fusion]] or [[thermonuclear weapon]].  Many tests of these weapons were conducted during the [[Cold War]], but most of these tests took place on remote Pacific islands that were US territories, or in the upper atmosphere.    These weapons massively exceeded the power of the [[fission]] bombs dropped on Japan.  Simultaneously, and as a civilian spinoff from the military program, there were developments in the production of efficient [[nuclear energy]] for civilian electrical generation. The threat of the use of nuclear weapons was a major issue in the [[Cold War]]. Today, the thirty-year threat of the use of nuclear weapons to prevent international aggression have been credited by many with helping avoid another world war.
