Ehud Barak hadn’t given a speech in months, and speculation was rife about what he was going to say when he took the stage at a prestigious policy conference in Herzliya, an affluent suburb of Tel Aviv, two weeks ago. Barak was one of Israel’s leading political figures for two decades, having served as the country's prime minister in the late 1990s and later as defense minister under Benjamin Netanyahu from 2009 to 2012. Was he about to announce a political comeback?

It turned out that Barak, a former special ops commando officer, had one last mission in mind: To take out his former boss and partner.

In his speech, Barak accused Netanyahu of cowardice, opportunism and fear-mongering. He warned that Israel's current government, arguably the most right wing in its history, was showing “signs of fascism,” and that if Netanyahu wasn’t stopped, Israel was on course to become an apartheid state. “The entire Zionist project is in grave danger,” he proclaimed. And the main source of that danger wasn't Israel’s external enemies, but rather its own democratically elected leader.
