This is in fact a good thing. Nuclear weapons are a great equalizer between large and small countries. [1] One of the great problems of history for tiny nations like Georgia or the Baltic states is that they have consistently been at the mercy of Russia. Nuclear weapons will allow them to fight the Russians on an equal level, and therefore deter the Russians from intervening as actively as they have in the past.  In the case of Iran and its neighbours, Iran’s position would actually be weakened if everyone in the region acquired nuclear weapons as the United Arab Emirates or Bahrain cannot compete with Iran conventionally, but could compete in a nuclear arms race. Wider uptake of nuclear arms would reduce Iran’s power and influence.  Moreover there is little evidence that this domino effect will happen. North Korea detonated its first nuclear weapon in 2006 but there has been no response from other countries in the region even though South Korea and Japan could have rapidly gone for nuclear breakout.
