World nuclear forces, 2009
At the beginning of 2009 eight nuclear weapon states possessed almost 10,200 operational nuclear weapons. Several thousand of these nuclear weapons are kept on high alert, ready to be launched within minutes. If all nuclear warheads are counted—operational warheads, spares, those in both active and inactive storage, and intact warheads scheduled for later dismantlement, these states together possess a total of more than 23,300 warheads.
44 countries have access to the fissile material and technology to build nuclear weapons. With the Nuclear Non-Proliferation Treaty jeopardized, nuclear weapons could quickly spread.
Several of these have put us on the brink of accidental nuclear war.
