There are few government policies that are so
financially ruinous that they cannot be made more so by a determined
politician. And this weekend, it was Ed Davey’s turn,
for the Lib Dems. His diagnosis – that the US is no longer a dependable ally
and relying on them to allow the use of missiles which are leased from the US
may make them potentially unusable – is accurate enough. His cure, however –
that the UK should develop a completely new set of missiles on its own – would add
vast amounts of additional cost to a programme which is already hugely
expensive. It would also have a lengthy timescale before it could be ready for
use, and one of the known unknowns is whether the US will remain a hostile
actor for the whole of that period.
Whether it would make the weapons any more usable is another
open question. Their value as a deterrent has always depended on a series of
assumptions. That the UK has the ability to fire them at all without US permission
is certainly one of those, but there are others: that ‘the enemy’ will
simultaneously be mad enough to launch a strike which will incinerate millions
and make large areas of the earth (maybe even all of it) uninhabitable and sane
enough to be deterred by the thought of millions of their own citizens being incinerated
in return; that the orders given to the submarine commander instruct him to
launch in certain circumstances and that the commander, contemplating the scale
of destruction already wreaked on the planet, would follow those instructions;
and that the enemy would not already have located and destroyed the submarine.
That’s a whole load of caveats, without even considering whether the system
would actually work
anyway.
All of that matters only if the possession of nuclear
weapons had anything at all to do with war, peace or deterrence. If, as many
suspect, it’s actually more to do with a post-imperial mindset amongst UK
politicians – Labour, Tory and Lib Dem alike – that still doesn’t accept the
reduced status of the UK in the world and clings to the belief that what the UK
PM thinks is of any importance, then whether they work or not is largely
irrelevant; the important thing is whether the UK is accepted by other states as
being what its leaders think it is. It fails, though, even on that level. One
of the consequences of diverting so much resource into a single weapons system
is that the UK doesn’t have the sort of forces which can actually be of use,
leading to boats spending three days bobbing
about in the English Channel. Some of us might think that’s a positive, of
sorts – but I doubt that it’s what Davey had in mind.
