This is not spy school, and I'm not going to give away anything here that you couldn't find elsewhere on the Internet, but there are some standard policies of governments that make sense when you realise what they are protecting and why. I should point out that I refer to "UKUSA" as within this scenario the intelligence agencies are acting effectively as a team. It's not meant to imply anything else.
The first policy of any government is to make no comment. That is, you don't say something unless you absolutely have to. This works within intelligence, the treasury, press briefing guys, your local highway department, the whole shebang. It is easier to say "no comment" than even attempt to make a slight comment. The reason for this is that if you start discussing something, if a journalist pushes a goon into an area of discussion where security may be compromised and they THEN start "no comment"'ing, the journalist/spy/whoever can make obvious deductions. Imagine the following conversation between a journalist and a government goon:
Journo: Is that submarine over there a Trident nuclear submarine?
Goon: Yes, it is
Journo: Does it have nukes on board?
Goon: Yes, it has. They all have. You know that.
Journo: Is it true there is a submarine on patrol at the moment off the coast of country "X"? [X being a relatively friendly country]
Goon: One has docked in X for emergency repairs.
Journo: And is there one in the Gulf on patrol?
Goon: No comment
Straight away, you know that submarine movements in the Gulf are "hush hush", and it's almost certain that there is indeed a submarine in the Gulf on patrol and nobody wants you to know it's there. Don't blame them. You'd probably post a diary entry about it up here. Imagine the conversation if it went like this:
Journo: Is that submarine over there a Trident nuclear submarine?
Goon: No comment
Journo: Right. We can both see it. Does it have nukes on board?
Goon: No comment
Journo: Is it true there is a submarine on patrol at the moment off the coast of country "X"?
Goon: No comment
Journo: And is there one in the Gulf on patrol?
Goon: No comment
See how now, the fact that there is a sub on patrol in the Gulf disappears? The security of that submarine has not been compromised. It seems stupid that a goon won't accept that several hundred tons of metal in front of him may or may not exist, but the overall method is sensible.
Next, we have partial release. This is a risky business. You see, you can release just a little too much information that can then be built into a profile of a country's actions. Let's suppose the UK and the US announce they have firm intelligence of WMD in Iraq. This is partial release - Iraq is now aware that UKUSA are spying on it. They now need to work out how they know WMD is present, so they can engage in counter-surveillance. Already, UK/USA have given a huge amount of intelligence away - they have made the ultimate mistake of tipping off the target.
Let's then suppose that the press push a little more for what the evidence is. UKUSA decide to throw them a bone. They have copies of shipping records for components for WMD devices being sent into Iraq from the early 90's (this is an example - I'm not sure if they have or not in reality, but they certainly know about stuff back in '86). They tell the press this. Oh boy where do we begin as to what happens now. All of the following is the minimum impact:
- Iraq is aware shipping is being monitored
- Other 'unfriendly nations' know it is likely their shipping is being monitored
- The person who obtained the shipping information is now compromised as an agent of UKUSA intelligence agencies, and may possibly be in extreme danger
- The shipping company is now know to have weak security on confidential information, or they work with intelligence agencies, meaning they are in extreme danger as is all their property within Baghdad and other ports in unfriendly nations
- If UKUSA have access to shipping into Baghdad, they probably have many live agents working on other information gathering exercises there
- Iraq will now change their shipping conditions, so it becomes impossible for UKUSA to monitor their actions so easily.
- Other nations will secure any data they wish to hide around shipping operations
- UKUSA intelligence agencies have to change their entire methodology for tracking shipping into ALL these countries to counter-act the changes made by those countries
Not suprisingly, the decsion to give that one little piece of information away is now having massive effects. It's costing taxpayer's millions to change information gathering techniques, it's degraded diplomatic relations with half a dozen countries, several people's lives are now in danger, and several intelligence-friendly companies are now severly compromised. All because one photocopy from one shipping company, has been given to a journalist. All because we "need proof".
So, we say don't tell us all that nonsense, just give the UN directions to where the WMD is being developed. Sounds easy. It isn't. Let's suppose they give the UN that information, and the inspectors get into their jeeps and head straight to the first site. They find a biological warfare lab, developing Anthrax, Ricin, the whole shebang. Woop-woop! Let's have us a war! Not so fast though. The problem is, intelligence agencies, Iraq, everyone will want to know how the UKUSA guys knew it was there. The minimum impact, at best, is the following:
- Assumption: satellite intelligence was used, and is refined enough to watch people walk in and out of the building with WMD components. Result: All unfriendly nations hide their labs better, specifically make all operations at night in close-to-darkness to make it harder for this technique to work
- Assumption: Somebody on the inside squealed. Result: After the UN leave, all personnel at the site, whether they were aware of the existence of the bio-lab or not (it might be under a school after all), will be killed by local intelligence agencies.
- Assumption: Information leakage on documentation around the project confirmed the site's location. Result: All documentation around the project is destroyed, all unfriendly nations tighten up security, the UKUSA guys job's become a whole lot harder a year down the line when we move onto country "X" or whoever.
- Assumption: a defector to the UKUSA gave the intelligence about the site's location over as part of his asylum deal. Result: All potential defectors in all unfriendly countries are killed, thereby putting a stop to the most useful tool UKUSA have for gaining information.
- Counter-intelligence efforts raised in all unfriendly nations
- Diplomatic relations with half a dozen countries now break down
- Other countries demand UKUSA assist them in their "cause" (Israel/Palestine) and get annoyed that they wouldn't own up to having loads of toys in the past
- People start asking questions about budgets of intelligence agencies that are able to run such large operations
- Conspiracy theorists go nuts on believeable stories that if they know these sites now, that proves they must have known "X" back then and that "Y" was the case in 1974, and start spreading FUD about government intentions
- etc., etc., etc....
It's not just one of these that will be done, it's ALL of them. As a result, intelligence on future operations will become non-existent. It's difficult enough as it is to get defectors, perfect satellite intelligence, get insiders on-side, run agents in hostile nations, etc. without giving the game away to everybody about how you do it.
I suppose what I'm trying to say, is that there comes a point when if the CIA, NSA, MI6, GCHQ, whoever, say that there is hard evidence of WMD in Iraq you're just going to have to trust them. They're going to "no comment" on everything you ask them. They will not get into partial release, they will not give directions to the site. It compromises them, it compromises agents, it compromises every single component of a vast intelligence system that, in the UK at least, has taken over 400 years of experience to perfect.
Often, you assume that intelligence agencies want to lie to you, and can't be trusted. This is wrong. Politicians lie to you. The CIA used to lie to you because they hadn't got the hang of "no comment". These days, when they reveal something, you can guarantee it's been double-checked and they're taking big risks. They think it's worth it.
I know a lot of people will think I must be just the voice of the Man telling you not to panic. I can't say why you should just trust these people when they tell you WMD is in Iraq, but you should.
As a side-note, I really don't want a war in Iraq. I just think that the people supplying the idiots that are Bush and Blair with the hard intelligence, have probably got a point.
