Then perhaps they will have to agree on what they will discuss and what is taboo. This will probably drag until middle of next year. By then Israel would have bombed Iran, or dragged the US in doing so on their behalf, so all will be stopped again, and we are in for another few years of "regional conflicts". Eventually by the year 2020 things would have settled, and we will start all over again. Perhaps by then Pakistan will be the net "bad guy", so all options to delay concrete steps towards peace will remain intact.
