In a new USIP book, Ambassador Frederic Hof tells the story of a secret U.S. effort to broker peace between Israel and Syria between 2009-2011. Just as that effort seemed to be making important progress, Syrian President Bashar al-Assad's regime began to violently suppress Syrian protesters, scuttling the chance for peace. Hof discusses what the foundation of Israel-Syria peace would have looked like, the pre-2011 perceptions of Assad as a "reformer," President Biden's trip to the Middle East and how the international community should deal with the Syrian dictator today.
