My bet is never
There is no decision on a prize to be awarded yet except for bragging rights.
Keep a careful eye on the BBC world news. Tony Blair has changed his tune in the last few days. At a time when most of Europe and even his Labour party are against the attack.
This signales to me that it is imminent.
There is no reason for him to change his tune, unless he has been told "IT's a GO, so we expect your A$$ on board Tony, so get with the programme".
So I keep with my Original September 7th 20:00hrs Eastern Standard Time. (04:00hrs Baghdad time, New Moon).
