I don't think there is anything accidental coming from the Iranian government. They are saying at home that the election was fair, that it is the BBC/USA/Israel who have interfered in Iran and cast doubt on some fair elections, and that the CIA have murdered Neda Suliman to create a martyr.
It is likely that a majority of people in Iran will believe this. While just about everyone outside Iran thinks the results are wrong, it remains probable Ahmadinejad did win, though with a much smaller majority than is claimed. In Tehran and the big cities there are people watching the BBC's Persian service using the internet and communicating through twitter. But this is a poor and repressed country, and most people will want the stability and strength that they will think Ahmadinejab will offer.
I would love to think that the unrest would lead to a revolution bringing in freedom and democracy. I fear it will bring in a series of state executions of those demanding democracy.
In order to cement their regime Iran has to find an external enemy. Hezbollah is effectively Iran's terrorist organisation, and attacks in Europe or even the US are likely, where Iran seeks to show to its own people that it can strike at countries that it is saying are interfering in Iran. It is also likely that we will see baiting of Israel. Probably Iran will push ahead full speed with its nuclear programme, and in a very short time will be in a position to target Israel. It is quite likely that Israel will take early action, and this gives the Iranian regime the enemy they need to prop up their regime. Alternatively Iran will attack, cementing their regime by what they will see as a glorious attack on Israel, which will be applauded by many in the Islamic world and make Iran the acknowledged leader of a new militant and fundamentalist Islam.
It is all pretty gloomy.
