Yitzhak Rabin (1995)

The assassination of Israeli Prime Minister Yitzhak Rabin by Yigal Amir on 4 November 1995 was the single event that terminated the Oslo Peace Process just as it had a 60% chance of producing a two-state solution, based on polling at the time. Rabin, a decorated general with unparalleled security credentials, was the only Israeli leader able to make territorial concessions without being labeled a traitor. His death ended the realistic possibility of peace for a generation, a setback that remains more decisive than #5 King's in altering a national trajectory.
