Israeli Prime Minister Benjamin Netanyahu is having his prostate removed on Sunday, his office said, a procedure that comes as he manages multiple crises at once, including the ongoing war in Gaza and his own trial for alleged corruption.

Netanyahu, 75, is among a cohort of older world leaders, including U.S. President Joe Biden, 82, and President-elect Donald Trump, 78, whose health and physical fitness are under deep scrutiny both at home and abroad because of their advanced age and the effect that could have on their leadership.

Netanyahu, who has had a string of health issues in recent years, has gone to great lengths to bolster a public image of himself as a healthy, energetic leader. During his trial this month he boasted about working 18-hour days, even if those long hours are accompanied by a cigar. But as Israel’s longest-serving leader, such a grueling workload over a total of 17 years in power could also take a toll on his well-being.
