Small War of 2015
The so called Small War of 2015 was the largest use of nuclear weaponry on Earth ever. It is called small because it could have been so much worse. Of the millions of weapons that the nations of Earth had built over the years, only a dozen or so were actually detonated. The conflict, and the destruction, was limited to a handful of Middle Eastern countries. Death toll was in the low millions.
Within six months, the United Nations had collected, dismantled and stored in the Peace Vaults every weapon of mass destruction on the planet. Small arms followed within a decade. In 2025 Earth and the Human race experienced their first year without war. Future research was closely watched so that new and more sinister weapons could not be developed. Specifically, research into nuclear fission and fusion was all but abolished. However, other fields progressed rapidly, such as bio-technology, which led to major advances, including cloning and the creation of the Androsynth.
