Jeremy Corbyn. Demotix/Velar Grant. All rights reserved.Jeremy Corbyn, the new leader of Britain's Labour Party, has long been opposed to the country's possession of nuclear weapons. But he has also made it clear that this personal commitment does not extend to forcing this policy on the party he now heads. What he does want is an open debate and to convince others of the value of his views.
The replacement of the country's Trident nuclear system is now being discussed (see "Britain's defence policy: the path to change", 7 May 2015). If this were to go ahead and a similar system put in place, the development and lifetime costs will approach £100 billion. Almost everyone in the Conservative government and parliamentary party, and many Labour MPs themselves, believe that a replacement should be built and that Britain should remain a nuclear-weapons power. Yet there is a substantial minority across the electorate that agrees with Corbyn. This view has gained far more traction since it was adopted by the Scottish National Party, a shift prompted not least by the persistent campaigning of nuclear disarmers north of the border, including the Faslane 365 initative. Yet political polarisation means it will be difficult to realise Corbyn’s aims.
The pro-Trident position has an uncompromising military rationale. It entails keeping a ballistic-missile submarine on station and ready to launch at all times - what is called “continuous at-sea deterrence” (CASD). In turn this requires maintaining four submarines, in order to allow one available for round-the-clock patrol, as well as substantial naval back-up. The latter includes what is euphemistically called "deterrence support", an element that isn’t much talked about in polite circles.
