There is sonething very predictable about dealing with the ambitions if Islamic countries and that is their propensity for saying one thing and then doing the opposite.
The Iranian government cannot be trusted are obviously enjoying playing to a large audience of Islamic countries and see themselves as leading the "war" against the "evil" western countries
i.e. non Islamic countries.
You may be very certain of two things:
1. Iran will lie, and continue to lie about their nuclear ambitions, and
2. The international community will continue to dither hopelessly and endlessly right up to the first Iranian nuclear blast.
The only options to put a stop to this madness are obvious and not for the fainthearted.
