Kiev does not provide information to US intelligence, according to the NYT

Despite the massive aid provided so far, the United States is more knowledgeable about the Russian military’s moves and strategies than those planned by the Ukrainian general staff. This was revealed by some well-informed sources to the New York Times. Of course, notes the newspaper of the Big Apple: the Ukrainian president Volodymyr Zelensky provides daily social updates; viral videos show the effectiveness of Western weapons supplied; and the Pentagon also holds regular briefings on the progress of the war.
