Every country does whatever it wants in its own interest at the time. We still have little idea of the amount of hand-holding under the table.
We funded tribal chiefs which included members of the now 'Taleban' when it suited us to destroy the Russian invaders in Afghanistan. Now we have properties in Belgravia owned by Russians - and even football clubs.
I listened to Peking Radio spouting out to the assorted tribes of then Northern Rhodesia to throw off the shackles of the imperialist oppressor/bloated capitalist pigs and their running dogs. Now the country's got several billionaires, let alone millionaires, and it has replaced the imperialist oppressor in taking over rail lines and copper mines, none run with the slightest nod to Health, Safety, and the progress of the indigenous peoples. So much for the cant from Canton.
I have a friend who still won't buy Japanese cars because of how nasty they were in WWII, rather forgetting about the unpleasantness of Germany at that time. The Nippons were appalling to captive Australian troops, beheading and torturing many who didn't die from malnutrition, disease, and overwork, but now Oz encourages them in their thousands as tourists, where they are made most welcome. My friend's small gesture seems outdated and slightly absurd given the change wrought in a few decades.
Everything changes over time, which means shifts in allegiances in accordance with what's best for one's own position.
I can't think there's anything revealed about the Wikileaks scenario that has sent me reeling and in need of smelling salts. The Saudis a bit concerned about Iran? No shit! Would they like Ahmedinajad out of the way? Yes, of course they would. Like they'd have liked the Ayatollah Khomeini out of the way back in 1979, when he was exhorting Saudi Shi'ites to rise up against the imperialist oppressors and their running dogs (the Saudi royal family-cum-government). The eager purchasers of BAe Systems weaponry, equipment, and training nous has been tormented by native dissidents since the 1960s, through the 1970s in particular with the seige of Mecca and onwards by homegrown extremists - some who'd like the royals out and an even stricter regime imposed, some who'd like the royals out and a democracy instead of an autocracy. There are regular street shoot-outs in the country between Iranian-inspired or Al-Queda-inspired groups, but we hear little of it in the UK.
Prince Andrew a buffoon? Seriously? No, I'd always thought the British royals represented the most finely-tuned of intellects...
Governments have been brought down by leaked scandals, lest we forget the Profumo Affair, high-placed ministers ruined by tabloid smears involving their personal lives (Jeremy Thorpe, Lord Boothby, et al), you name it. Only last month, a 'very funny' book was published revealing the letters sent by British ambassadors in various outposts round the world, criticising the halitosis of this or that PM or Prez, the disgusting state of their lavatories, the backwardness of the people, etc., etc. And these were recent whines, not culled from 17C diaries.
It was inevitable that as soon as the Wikileaks appeared, there'd be the usual drum-beating about how there would be 'blood'. Why? One country's rep opining that another could do with being bombed? When Iran, for example, has quite openly and blatantly announced it'd quite like to see Israel 'wiped off the map'?
As for dissidents, I can't think there are too many of those not known to the types of governments which beget them. They'll be disappeared or murdered soon enough - lest we forget the ricin and plutonium murders right here in London by the KGB or its replacement oppressor? And that of Litvinyenko right at the time that English estate agents were eagerly selling off prime London real estate to his billionaire brethren from his utterly corrupted country, too. That's how well we protect dissidents, and that was without Wiki.
