Thanks Blistering. I don't typically read paragraphs that rely on 'sources' to 'disclose' details!

It reminds of a story from 2003, when the GCC states agreed to the goal of a unified currency by 2010.

I don't know which will happen first - a common currency, or a common visa system. My bet would be neither will ever happen, as long as the GCC states continue their fighting.
