Elon Musk pounded his fist to his chest and extended his right arm into the air during a speech Monday, which many have equated to a Nazi salute—while defenders say it was accidental.

In a post on social media, Netanyahu said that Musk is being “falsely smeared” and suggested that Musk’s support of Israel is proof that he isn’t antisemitic — even as numerous Jewish and anti-hate groups and observers have said that Musk’s now-infamous salute was clearly a Nazi salute.
