22 August is the date on which Iran promised to respond to UN demands that it shut down it's nuclear program.
It is also, this year, the day on which the Mohammedan commemoration of Mohammed's purported 'night flight' to 'the farthest mosque' and heaven. (The date on the civil calendar varies from year to year since the Mohammedans use an uncorrected lunar calendar.)
It is speculated that the 'response' will be something other than diplomatic, like an attack or a nuclear test.
Thanks.
It could be interesting. We'll have to wait and see.
