It was an “open secret” but not publicly acknowledged. And of course the statement made is one more on the pile of clear indications of genocidal intent, as well as an indication of people in high levels of the Israeli government advocating the reckless use of nuclear weapons, which I think absolutely raises huge questions.
Russia in general on statements on this conflict, is of course looking to discredit the U.S. and allies, but with the U.S. and allies being horrifically in the wrong in this situation, they don’t have to distort or be dramatic to accomplish that, tbph. My own personal take.
