The former Pink Floyd leader Roger Waters is a longtime critic of Israel, and he’s also been a vocal critic of Joe Biden in recent months, including Biden in a “war criminal” montage during his This Is Not A Drill tour. In interviews, Waters has blamed NATO aggression for Russia’s invasion of Ukraine, and he’s written an open letter to the first lady of Ukraine, encouraging her husband, President Volodymyr Zelensky, to sue for peace. In a Rolling Stone interview a few months ago, Waters claimed that he’s on “a kill list that is supported by the Ukrainian government.” Right now, some of Waters’ old collaborators are taking aim at him.
