The political event that radicalised me was the Miners' Strike in Britain during 1984-5. Before it I was a something of an alt-Righter avant la lettre; afterwards I drifted steadily left to the point that I became a fellow-traveller of the CPB-ML for a time, and remain very much to the left of the Labour party and have fallen off the legitimate political spectrum in the US altogether. Seamus Milne's book goes a long way towards explaining why.
The starting point of Milne's book is the broadcast on 5 March 1990 of 'The Cook Report', an investigative journalism programme shown on Britain's Independent Television Network. This presented some serious allegations about money that was supposed to support the miners during the strike instead being diverted to pay off debts of key leaders of the National Union of Mineworkers -- the president, Arthur Scargill, Peter Heathfield, the general secretary, and chief executive Roger Windsor. Windsor himself was the source of these allegations. As well as the television broadcast, the matter was taken up with enthusiasm by the Daily Mirror, owned by the fake tycoon Robert Maxwell. The British media, never one to support working-class self-organisation, leapt enthusiastically on the claims, which were given widespread coverage. Scargill's reputation, never high among people outside the Labour movement (nor within certain quarters of it either), was besmirched to the extent that it has never really recovered.
This is the problem Milne's book seeks to address. The allegations were total tosh. Chapter-by-chapter, Milne analyses the claims, reviews the evidence and concludes that there was nothing to it. The reality, in fact, was that the media didn't care about 'the truth'. All that mattered was the overall strategic goal, which was to destroy the capacity of the trade union movement to advance its claims to represent the interest of its members. The most powerful union in this regard had been the NUM, and its leader retained some clout within his constituency. The media campaign against him lasted some six months before it was quietly abandoned. The way propaganda works is to make a big noise at first, while the painstaking refutation of the 'evidence' is in its nature more subdued and piecemeal. (It's worth noting that Watergate, the exemplar of investigative journalism of the abuses of the powerful, emerged in a subdued and piecemeal way.) The campaign was a success insofar as most people remembered the allegations, and less recalled the refutation.
The nature of the tale is such that the book lacks a strong narrative flow. Instead, the thematic approach resembles a legal case during which the constant question is 'cui bono?'. The chapters build up from the original Cook Report broadcast, following from that moment to cover the specific allegations, its sources, the journalists and the role of Maxwell, the role of the Soviet Union and finally ending with the actions of the British Secret State, in particular MI5. Following Milne's research, it's hard to reject the idea that Cold War national security was the justification behind the security state's war on the Miners' Strike, despite it being quite obvious throughout that the Soviet government was none to keen on wholehearted backing of Scargill's strategy. In fact, it was a war against the serious threat that the left of Labour presented to the Establishment within a democratic system of party competition. The risk of the Labour party falling under the sway of the Left was too high, regardless of whether or not politics within the Labour party made such a scenario plausible. (The useless double-loser Neil Kinnock had made it clear he was not of the Left as of 1984, so it was actually fairly implausible, especially given the bad result the party had suffered in the 1983 general election.)
Milne's book reinforces my opinion that we in places like the United States, Canada and Britain don't live in the kinds of democracy that they teach us at school. There are carefully defined limits to what the Establishment will accept. If people push at those limits in a manner completely legitimate under the system, they will be slapped down by the full power of the police and security state. Far from listening to what MI-5/MI-6, the FBI/CIA or CSIS have to say, we should treat every pronouncement from them as a total lie and demand to see the evidence. Even if you hate the target of these national security voices, you should still utterly reject what they have to say. They are poisonous toads who are uninterested in a proper democracy.
