"All I can say is: be careful! You don't play Russian roulette with Germany's security," Scholz said, claiming that Merz wants to give Russia, a nuclear power, an ultimatum about possible transfers of long-range Taurus missiles.Scholz's statement comes as Germany faces political turmoil, with opposition criticising the Chancellor's consistent refusal to send German-made Tauruses to Ukraine. During the conference, Scholz emphasized the importance of a calm and measured approach, according to the report. When it comes to questions of war and peace, cooler heads are needed, Scholz said. He promised to remain "steadfast and level-headed."Scholz also stressed that real negotiations on a possible peace plan should not take place "over the head of Ukraine."Merz, the parliamentary leader and chancellor candidate of the center-right CDU/CSU party, has previously spoken in support of sending Taurus missiles to Ukraine.
