The date in the URL (2001-01-01) might be the original publication date - it isn't the declassification date (which was 2014/09/03). The previous URL indicates the article was originally published in Studies in Intelligence, Vol 45 No 3. The CIA has tables of contents for issues from 2002 onwards (https://www.cia.gov/library/center-for-the-study-of-intelligence/csi-publications/csi-studies/studies https://www.cia.gov/library/center-for-the-study-of-intellig...), which suggest that there is one volume per year and 2002 was volume 46. This is at least consistent with publication in 2001. Edit: it would be surprising if the 3rd issue of the year was published on the 1st of January. Most likely part of the publication date was entered, and the day and month left at the default value 1. Edit 2: also, the article refers to being written "fifty years after the outbreak of the war", which would be roughly 1950+50 = 2000.
