Arms supply and security: Germany's position German Defense Minister Boris Pistorius said that the country can no longer supply Patriot systems to Ukraine due to the risk of gaps in its defense. According to him, the systems that have already been delivered and the guided missiles have depleted the German reserves. This has become a serious dilemma: whatever is given now will be temporarily impossible to repay. Pistorius also stressed that some countries contributed less and Germany expected the partners to step up their efforts. Russia news.
