.FOR MONTHS Olaf Scholz, Germany's chancellor, has stood up to residential and worldwide pressure to offer Ukraine with German-made Taurus boat trip projectiles, a precise, long-range munition. Hopeless to aid an increasingly beleaguered Ukraine, some allies have cooked up brilliant schemes to help change Germany's mind. David Cameron, Britain's foreign assistant, has hinted his openness to a plan that would find Germany send out Taurus missiles to Britain, therefore making it possible for Britain to send even more of its own Storm Vestige cruise line projectiles to Ukraine. Yet Mr Scholz declines to move. What are Taurus missiles-- and why is actually the German federal government thus hesitant to send them to Ukraine?
