American filmmaker Oliver Stone, who met Netanyahu, called him crazy: “Netanyahu is crazy. I can say it again. To me, he’s crazy. I met him a few years ago when he wasn’t prime minister. I interviewed him. And at the time I said to myself that he was crazy. But since then it’s gotten much, much worse. He’s an absolute lunatic. I’ve never seen such carnage!” Source: Global News (EU, USA)
