I've written a few times about the phenomenon of western European and American journalists and commentators appearing on the state-run media outlets of autocratic regimes, such as Press TV, RT, CCTV 9, and the like, and the moral hazard inevitably involved in doing so. Whilst I'm willing to accept the protests of those who say that appearing on these channels does not mean that they actually support the regimes that control their editorial content, it really is hard to believe that these people were not guilty of (at minimum) extreme naivety and incuriousness.
It is therefore with very little surprise that I read that (left-wing hopeful for the leadership of the Labour Party) Jeremy Corbyn regularly appeared on Press TV in recent years (he stood in for George Galloway), even after Press TV's activities during the Iranian regimes repression of the Green Revolution caused many to question whether it was appropriate to appear on this channel. To quote one journalist who refused to appear on the channel: "it seems to give legitimacy to a regime that treats its own people like sh*t and spreads poison and violence around the world".
The comments made by him when appearing on the channel that have caused the most controversy (that Bin Laden's death was a "tragedy") are actually defensible - whilst few tears were shed over Bin Laden's demise, it would have been better if he had stood trial. What for me is very difficult to defend (or even comprehend) is how Corbyn could have, in good conscience, appeared on a channel that has previously trumpeted holocaust-denial and defended the execution of people for the 'crime' of being gay, a channel that had previously broadcast the torture-extracted 'confession' of an Iranian human rights activist to working with foreign 'spies' disguised as journalists. This, by itself, should cast doubt as to whether he is at all suited to high office in a democratic country like the UK.
Unfortunately, Jeremy Corbyn's supporters seem totally immune to evidence of his unsuitability as Labour party leader, which is legion, so knowledge of his appearances on Press TV is unlikely to shake their resolve either. I totally agree with Alex Massie that the likely outcome of his selection as party leader (which now seems inevitable) will be a total slaughter at the polls in 2020. However, there is always the risk in politics that some disaster will tip one party out of power and another in, regardless of how suited it is for rule, so there is always the possibility, albeit slim, that this man might one day become the leader of the UK - and that would be a disaster compounded by a disaster.
[EDIT: Interestingly, Jeremy Corbyn has declared at least two payments of up to £5,000 in recent years from Press TV for appearances]
