The common claim that Iran’s missile development must be stopped altogether because these systems could deliver nuclear weapons in the future rests on broad generalisations. While there is reason for concern, priority attention should be given to those missiles that might realistically be used for such a purpose, if Iran were to go down a perilous nuclear path.
The international standard – but not treaty – for determining the inherent nuclear capability of missiles is the threshold developed in 1987 by the Missile Technology Control Regime (MTCR), which seeks to forestall exports of missile systems able to deliver a 500kg payload a distance of 300km or more. Eight of Iran’s 13 current ballistic missile systems – the largest and most diverse arsenal in the Middle East – exceed this threshold and are thus deemed to be nuclear capable. The other five, all within the Fateh-110 family of missiles, are certainly lethal, especially when shipped to Hizbullah for use against Israel, but they are clearly not intended for nuclear use.
