AFTER the temporary peace deal between the US and Iran is physically signed in Geneva on Friday, an arduous process of negotiations begins between both parties to flesh out the nitty-gritty of a long-term arrangement for peace. At present, there are many unanswered questions that have been deferred for later, such as the status of the Strait of Hormuz, and the future of the Iranian nuclear programme. Suffice it to say, both parties must exercise a degree of flexibility if there is to be long-term peace between them.
