"During the 1990s, the Middle East had witnessed a decade of relative calm, in part thanks to the détente between Iran and Saudi Arabia but also as a result of Pax Americana—post–Cold War, the United States was the unchallenged hegemon. The Saudi-Iran rapprochement had yielded more than anyone expected, including a security agreement. When Saudi Arabia’s defense minister visited Tehran in May 1999, his Iranian counterpart declared: “The sky’s the limit for Iranian–Saudi Arabian relations and cooperation as the whole of Islamic Iran’s military might is in the service of our Saudi Muslim brothers.” President Bill Clinton was basking in the glory of a unipolar world and America was prospering as the indispensable nation. Throughout his presidency and until his very last months in power, Clinton was working on peace between Arabs and Israelis—succeeding only with the Jordanians. Even though people like Nasr in Egypt had their lives upended, Iraq was under UN embargo, and bombs had gone off in the Saudi kingdom, the decade carried some promise. It all came to an end on 9/11. President George W. Bush went to war against the Taliban, who were sheltering Osama bin Laden. After liberating Afghanistan, America declared a global war on terror, a frenzy of liberation. Bush decided to finish what his father had begun—he went after Saddam."
