European leaders have warned that the United States could betray Ukraine and Europe, according to a leaked phone call. The leaders discussed growing concerns about a potential shift in the US stance on Ukraine following the presidential election. They expressed worry that a new US administration might reduce military aid or begin negotiations with Russia without consulting allies. One participant noted that such a development would be a 'catastrophe' for European security. The call also addressed the need to strengthen unity among European nations for potential negotiations with the future US administration.
