Some basic, useful information is that there are numerous such individuals. Perhaps it would be more difficult to assemble here a similar list of Dutch or Danish citizens of note. Bias is present in such an assessment - one has to reckon with the distortion of the dominant English-language media. Great Britain is also pulling a lot of weight in Afghanistan, so for that reason, too, more individuals of note could be expected from their part, in any case. And so on.
Sir Sherard Cowper-Coles: He is Britain's ambassador to Afghanistan. He said some rather pessimistic-sounding things about the host country - if it is true what Le Canard Enchaîné reported in October. That is: what was leaked to them somehow. Information supposedly revealing the contents of a confidential cable sent to French President Nicholas Sarkozy, summing up notes taken by someone at a meeting between Ambassador Cowper-Coles and the deputy French ambassador, Francois Fitou, in September, 2008, in Kabul. Ambassador Cowper-Coles is thus claimed to have said that "American strategy is destined to fail," and to have warned that increasing troop levels would serve only to "identify us even more clearly as an occupying force and multiply the number of targets". And then he is claimed to have added: "The foreign forces are ensuring the survival of a regime which would collapse without them. In doing so, they are slowing down and complicating an eventual exit from the crisis." His conclusion is reported to have been that Afghanistan should be "governed by an acceptable dictator."
Brigadier Carleton-Smith: As a commander of the British 16 Air Assault Brigade, which has completed a tour of Afghanistan by autumn, 2008, seemingly contributed to the wave of pessimistic comments himself. He said, on October 5, 2008: "We're not going to win this war. It's about reducing it to a manageable level of insurgency that's not a strategic threat and can be managed by the Afghan army. We may well leave with there still being a low but steady ebb of rural insurgency." He actually didn't say that the war in Afghanistan was doomed from a Western perspective. But since he noted that there is a need to talk to the Taliban, many papers quoted him in articles also mentioning Ambassador Cowper-Coles' comments. See for instance here.
Daniel James: The man on the left, by the name of Daniel James, is accused of having spied for Iran. He is a British citizen, with a very British-sounding name, but in fact he was born in Iran, and got to the position he was in (interpreter for General David Richards, the British commander of NATO forces in Afghanistan), at the time when he was arrested in December, 2006, since he spoke fluent Persian. He was an interpreter and he is alleged to have interpreted as his task to forward some sensitive e-mails and the like. He is said to have sent coded e-mails and to have made phone calls to the Iranian military attaché, Colonel Mohammad Hossein Heydari. His case was heard at a London court on October 13, adding to the gloomy UK picture of what's going on in Afghanistan, at a moment when there already was much gloomy chatter.
Rashid Rauf: A suspected British Islamist militant, Rashid Rauf was killed in Pakistan in November, 2008, in one of those US air strikes usually killing Al-Qaida number-threes and the like. He wasn't a specific target of the drone-executed assassination, but he did end up killed. He was wanted in connection with the 2006 trans-Atlantic plot. An American cross-border strike against a British cross-border-insurgent in Pakistan was certainly of interest for the British public.
Kim Howells: I wrote of him just yesterday. He was a minister (by FO denomination), responsible for a long while for the Afghanistan brief at the British Foreign Office. And he also said some rather pessimistic-sounding things about Afghanistan, and some rather negative things about Hamed Karzai.
Which makes me realise that this post of mine wasn't so random in fact. It looks just like an ideal follow-up (or follow-back) in a way. Common themes: UK dislike of Hamed Karzai, heart-of-darkness pessimism, random unfortunate and inconsiderate acts and speech-acts etc. Altogether, it's something like a cascade (the way James Rosenau conceived of it).
Meanwhile, for some interesting flavour, some Iranian and Pakistani immigration was/is added to the mix, to make this selection of British citizens of note with regards to (and not necessarily in) Afghanistan more interesting.
Ok, that's it from me, for today, for an analysis.
