There’s just something about Vladimir Putin wishing someone “good health” that makes it seem their health has never been in more immediate danger. The Russian leader has responded to President Joe Biden’s description of him as a “killer” by ominously telling reporters that he hopes Biden remains healthy, and adding: “I say that without irony and not as a joke.” Biden’s comment, made to ABC News in an interview broadcast Wednesday, has provoked fury in Russia. Konstantin Kosachyov, the deputy chairman of the Russian parliament’s upper house, said that Biden’s comments were unacceptable and he expects an apology, adding: “This kind of assessment is not allowed from the mouth of a statesman of such a rank. This kind of statement is not acceptable under any circumstances.” Kremlin spokesman Dmitry Peskov told reporters on Thursday: “These are very bad remarks on the part of the U.S. president.”
