We longtime U.S. intelligence officers again wish to convey our concerns and cautions directly to you prior to a critically important NATO summit – the meeting that begins on July 8 in Warsaw. We were gratified to learn that our referenced memorandum reached you and your advisers before the NATO summit in Wales, and that others too learned of our initiative via the Sueddeutsche Zeitung, which published a full report on our memorandum on Sept. 4, the day that summit began.
