US President Donald Trump has questioned the effectiveness of large-scale arms supplies to Ukraine, saying the West has yet to get the expected results. The American leader spoke about this in an interview with CBS News, published on Sunday. During the conversation, the journalist reminded Trump that thanks to Washington's military assistance, Ukraine was able to maintain its independence. However, the US president disagreed with this assessment and said that it was too early to talk about the results achieved. Separately, the American leader explained the mechanism of supplying weapons to Kiev. According to him, the US remains the main supplier of weapons, while European countries pay for their purchase. Trump clarified that Washington sells weapons to European countries at full cost, and then they transfer them to Ukraine.
