Germany's president on July 9 said the country should not "block" the United States from sending cluster bombs to Ukraine, while defending its opposition to the use of the controversial weapon. "Germany's position against the use of cluster munitions is as justified as ever. But we cannot, in the current situation, block the United States," President Frank-Walter Steinmeier told German broadcaster ZDF. If Ukraine no longer has the means to defend itself or if those supporting the war-stricken country back down, "it would be the end of Ukraine," said Steinmeier, whose powers are largely ceremonial.
