The joint Israeli-US attack on Iran yesterday is a colossal risk. Ideally, the regime in Iran will fall, following a battering on the battlefield and a popular uprising, and, in the fullness of time, a new moderate government will be formed. The Iran of the past 50 years, one which sponsored terrorist organisations, demanded an end to the State of Israel and repressed its own people is one which will not be missed.

On the other hand, a situation like that which emerged after the Iraq war earlier this century could create huge instability and regional wars that could go on for decades. This is another possibility. 

All manner of scenarios are possible, some leaning towards greater stability and peace, others away from it. I hope for the best, of course.
