In Tomorrow Is Yesterday, the analyst Hussein Agha and the diplomat Robert Malley offer a personal and bracing perspective on how the hopes of the Oslo Peace Process became the horrors of the present. Drawing on their experience advising the Palestinian leadership (Arafat and Abbas) and US presidents (Clinton, Obama, and Biden) and their participation in secret talks over decades, Agha and Malley offer candid portraits of leading figures and an interpretation of the conflict that exposes the delusions of all sides.
