 Biden and Schultz worried that allies weakened support for Ukraine at critical moment of war. US President Joe Biden has expressed concern that allies are weakening their support for Ukraine at a critical time in the war with Russia. Biden said that Russian President Vladimir Putin was on the balls of his heels. And what are we doing? Stepping back, he said. Biden warned that Ukraine is at a critical point in the war as the country's ammunition and weapons stockpiles are dwindling and fighting is expected to intensify this spring. The United States is viewed as we are the essential nation. If the United States steps out of events, what happens? What happens then in the Middle East? The Taiwan Straits. What happens in Asia? What happens with Ukraine? The American leader said. Despite Western support, Ukraine is likely to face a serious shortage of weapons and ammunition soon, states German Chancellor Olaf Scholz. The European Union and its member states have been Ukraine's largest financial supporter, having contributed more than $91 billion since the beginning of the war, followed by the US and Germany. Germany's military support is second only to the Americas, he said. According to the chancellor, since the beginning of the war, the German government has allocated purchased and supplied Ukraine with military equipment, including tanks, artillery and expensive air defense systems worth more than $30 billion. Our message is clear. We have to do our utmost to prevent Russia from winning. If we don't, we might soon wake up in a world even more unstable, threatening and unpredictable than it was during the Cold War, Scholz stated. He noted that some financial obligations have already been exhausted while others need to be extended. Despite our support, Ukraine could soon face serious shortages in arms and ammunition. Some financial commitments have already run out and others need to be extended. The long-term consequences and costs of failing to stop Putin's aggression would dwarf any of the investments that we are making now, he emphasized.
