Gentlemen don't read other gentlemen's mail
The news that British spies bugged the office of Kofi Annan during the Iraq debate has a number of implications. First, for me, this is the point at which Tony Blair should go. The whole idea of going to the UN for authority to invade Iraq was his, not Bush’s, and now it’s clear that it was corrupt from the beginning. I won’t argue this in detail – no doubt a lot of people already thought he should go, and others still won’t be convinced.
The main point I want to make is that it’s time for Britain to get out of the spy game. More than any other democratic country, Britain is addicted to spies and their natural counterpart, Official Secrets. From Burgess and McLean to the present day, the spies have been a constant cause of embarrassment and worse. On the other hand, there’s no evidence that they’ve ever found out anything that was both useful and sufficiently reliable to act on (in this context, I’m excluding wartime codebreaking, which is always useful since, at a minimum, it disrupts enemy communications).
This isn’t a matter of bad luck, or even incompetence. Standard game-theoretic reasoning shows that, outside the zero-sum case of war, there’s unlikely to be a net benefit from actions like bugging offices. The problem is simple. If I bug your office and you don’t suspect me, I can gain potentially valuable information that you don’t want me to have. But if you suspect me, and I don’t suspect that you suspect, you can use my bugs to mislead me. As with all game theoretic reasoning, you can iterate this as many times as you like, but the end result is that the net value of information derived from bugging is zero. On the other hand, the costs of the activity are substantial. In an environment where bugging is routine, everyone learns to communicate in various forms of code, and decoding is costly and prone to error.
He’s often been dismissed as hopelessly naive, but US Secretary of State Henry Stimson was right when he shut down the State Department’s cryptanalytic office saying “Gentlemen don’t read each other’s mail.”
I’ve treated Clare Short’s allegation as fact, since Blair hasn’t denied it. His claim that he can neither confirm nor deny it for security reasons doesn’t hold up. Short made the specific claim that she had seen transcripts of Annan’s conversations. Blair could refute this claim without reference to whether or not such transcripts existed.
The argument about the uselessness of spies is developed at much greater length in this piece I wrote for the Australian Financia Review The conclusion:
The spy myth clearly served the interests of intelligence agencies, which prospered during the 20th century more than any set of spies before them. The real beneficiaries, however, were the counterintelligence agencies or, to dispense with euphemisms, the secret police, of both Western and Communist countries. The powers granted to them for their struggle against armies of spies were used primarily against domestic dissidents. Terms such as ‘agent of influence’ were used to stigmatise anyone whose activities, however open and above-board, could be represented as helpful to the other side.
The supposed role of the secret police, to keep secrets from opposing governments, was, as we have seen, futile. Secret police, and the associated panoply of security laws, Official Secrets Acts and so forth, were much more successful in protecting their governments’ secrets from potentially embarrassing public scrutiny in their own countries.
As spies and the associated fears have faded in their public mind, their place has been taken by terrorists. In many ways, this is a reversion to the 19th century, when the bomb-throwing anarchist was a focus of popular fears and the subject of novels by such writers as Chesterton and Conrad.
As the attacks of September 11 showed us, the threat posed by terrorists is real. Nevertheless, even if terrorists were to mount attacks ten times as deadly in the future, they would still present the citizens of the Western World with less danger than we accept from our fellow-citizens every time we step into our cars.
If the century of the spy has taught us anything, it is that we need to assess the dangers posed by terrorists coolly and calmly rather than giving way to panic.
