German Chancellor Olaf Scholz gave an angry rebuff to the idea of sending long-range Taurus missiles to Ukraine amid the fallout of a Russian-orchestrated leak of internal German debates that exposed sensitive information about the United Kingdom’s involvement in the war in Ukraine.

“It is unacceptable to supply a weapon system capable of reaching great distances without considering how to control it,” Scholz said Monday, according to media translations. “If you want control, it only works with the participation of German soldiers, so for me, this is out of the question.”
