It seems to me a reasonable person reading those two paragraphs will understand them as a saying that Israeli intransigence about Jerusalem caused the negotiations to fail, and as a result the Iranians are trying to develop nuclear weapons; also, absent the failure 9/11 wouldn't have happened, the recession wouldn't have happened, there wouldn't be wars in Iraq and Afghanistan or bloodshed in Pakistan Somalia and Yemen, nor would there be terrorism or extremism.
... However, the deal broke down over the issue of Jerusalem as the result of Israel’s insistence that it was the “eternal, undivided capital of Israel”. If agreement had been reached at that summit, the history of the past ten years would have been completely different from what it has been. The Israelis and Palestinians would have experienced a decade of peace and security. We would not be talking about the presumed danger of an Iranian nuclear programme, or the estrangement between Turkey and Israel, and we probably would not have witnessed the terrible events of 9/11or the invasion of Iraq and Afghanistan.
Instead, the world is going through very difficult times at present. The global economic recession, which according to the Nobel Laureate Paul Krugman could yet go through a double dip recession or even a depression,2 the ongoing wars in Iraq, Afghanistan, Pakistan, Somalia and Yemen, the continuing Arab-Israeli conflict, and the scourge of international terrorism have produced a situation more dangerous than at any time since the Second World War. All these events are fuelling extremism on both sides. On the one hand, the Israelis are talking of the existential threat that they face from a future Iranian nuclear bomb, and on the other hand we hear talk of a Zionist conspiracy and a Jewish-Christian crusade against the Muslims.
That's what the professor is saying, isn't it?
