German Chancellor Olaf Scholz called on Russia to rule out the use of nuclear weapons in its war against Ukraine. "It is not permitted, it is unjustifiable, to use nuclear weapons in this conflict," Scholz said at a convention of his Social Democrats party in Berlin on November 5. "We call on Russia to clearly state that it will not do so. That would be a line that must not be crossed." A day earlier, during a visit to Beijing, Scholz, together with Chinese President Xi Jinping, warned against nuclear escalation, calling nuclear threats "irresponsible and incendiary."
