"If Iran becomes a nuclear weapon state it is the end of non-proliferation as we know it. If Iran gets a nuclear weapon you are likely to see Saudi, Egypt and other countries follow suit and we will bequeath to the next generation a nuclear arms race in the world's most unstable region"

This quote by Liam Fox recommends that if Iran were to become a nuclear weapon state, it would have a domino effect on other countries in the area. It implies that if Iran were to get nuclear weapons, other nations such as Saudi Arabia and Egypt would likely do the same, leading to a nuclear arms race in the Middle East. This would be a harmful circumstance, as the Middle East is currently one of the most unsteady regions in the world. The quote also recommends that if Iran were to become a nuclear weapon state, it would be completion of non-proliferation as we understand it. This indicates that the current system of non-proliferation would be rendered inefficient, which the world would be facing a new and more dangerous truth.
