Forgotten
Some stories come up on the news and then seem to be forgotten.
When Vladimir Putin visited Tehran in mid-October [16 Oct], it was reported that he had made a "significant offer" regarding Iran's nuclear programme, in a meeting with Iran’s supreme leader, Ayatollah Ali Khamenei, according to Ali Larijani. By the following weekend (20/21 Oct), the Iranian president, Mahmoud Ahmedinejad, denied that any such offer had been made (BBC World Service news bulletins).
It was hardly any surprise then, when Larijani was replaced as nuclear negotiator.
Update (9 Dec)
While the threats of the Turkish army to intervene on a larger scale in northern Iraq rumbled on, another thing that I did not hear mentioned, that may have affected the Iraqi Kurds ability to act against the PKK themselves, was that early in the year numbers of Kurdish forces redeployed to central Iraq as part of the 'surge' in and around Baghdad. Reports in early-December indicate that the Peshmerga have taken action, cutting off supply routes to the PKK (BBC WS).
