Nuclear weapons debate
After the bombings of Hiroshima and Nagasaki, the world’s nuclear weapons stockpiles grew, and nuclear weapons have been detonated on over two thousand occasions for testing and demonstration purposes. Countries known to have detonated nuclear weapons—and that acknowledge possessing such weapons—are (chronologically): the United States, the Soviet Union (succeeded as a nuclear power by Russia), the United Kingdom, France, the People's Republic of China, India, Pakistan, and North Korea.
Nuclear famine
While the total number of global nuclear weapons had declined by two thirds following the U.S.-Soviet Strategic Arms Reduction Treaty (START) compared to the early 80s, some experts feel that the risk of nuclear conflict has not decreased, but has instead risen. This is due to nuclear proliferation as more countries such as India, Pakistan, and North Korea now have nuclear arsenals, increasing the risk of regional nuclear conflicts. Growing military tensions, accidents, sabotages and cyber-attacks are all potential trigger points of massive nuclear disruption and regional, if not global famine.
