Should the case against the Libyans be overturned?Not on this evidence, no.
Though at the time of the Lockerbie trial, there were significant suggestions (extenvie coverage in
Private Eye magainze, which isn't infallible but often breaks stories that take
years to surface in the mainstream) that there was indeed a conspiracy involving US security services.
The tale went (as far as I recall) that Ghaddafi of Libya was desperate for Western trade for his oil, which had been blocked since his country had made a habit of killing Westerners, Americans especially. He was quite prepared to offer up a sacrificial lamb, especially since the trial would take place in Scotland and not the USA (so the "fall guy" would not face the death penalty), and denounce his prior support for international terrorism (including the IRA, who were already beginning to distance themselves from terrorism) in order to get some much-needed capital.
At the same time, the "real" culprits were Syrians, who had become diplomatically useful to the USA in the ten years (or so) between the bombing and the trial. Something to do with a settlement in Lebanon at the time that required Syrian withdrawal, their price for which was not pursuing the real Lockerbie bombers.
So, the story goes, the evidence was fabricated to frame the Libyan suspects, with the collusion of the Libyans, Syrians, and with the (at least) acquiescence if not outright cooperation of MI5. Crucial to the conspiracy was that the Scottish police, lawyers and courts were completely in the dark, so that the integrity of the criminal investigation and trial would be beyond question.
Jim Swire (mentioned in the article, and father of one of the British victims of the bomb on Pan Am flight 103) has been advancing this theory more or less ever since the arrest of the Libyan suspect.
I have to say I found this theory plausible, but didn't think about it much beyond that. It's just the usual sort of
realpolitik that's been going on since nation states were invented. But then the British are generally more cynical than many other nationalities, and I'd put myself forward as a more than usually extreme example.
Do they hate us because of our blue eyes , blond hair and our "freedoms"? No more than "we" hate "them" for their brown eyes, black hair and "religious certainty". By which I mean some of "them" (and some of "us") probably do hate "us" (or "them), but that's a gross oversimplification stemming from wilful ignorance. Most of the hatred on both sides arises for much more complex reasons, and most people on both "sides" aren't
on a side, and don't hate anybody.
Besides, nobody involved in this conspiracy, even if it is true, is now an active participant in the War on Terror. Ghadaffi's Libya has been careful to stay on-side since its global reentry into trade, and especially since he saw what happened to his some time ally among "non-aligned countries", Saddam Hussein, and his fellow sponsor of international terrorism Osama bin Laden, since 9-11. Both are powerful incentives for him to keep on the international straight and narrow.
Syria has walked the line officially, though has made enough wobbly noises to be worthy of suspicion, but (if the conspiracy theory holds water) the USA cannot possibly pursue them for Lockerbie now without doing themselves a great deal of damage and rewinding the last 30 years of Middle Eastern diplomacy.
Either way, the "they" who planted the bomb on flight 103 is not the same "they" that's trying to shoot, blow up and generally kill or injure "us" now in Iraq, in Afghanistan, and in superficially normal urban and suburban family homes among us. Today's "they" is not the same "they" as it was 20 years ago, nor will it be the same "they" in 20 years time.
