After examining the Harmony database document you have stated “The document does not indicate which year he did the visit but it is for sure after the year 1995 based on the context of the document. Other reporting from different sources said that there is an indication that Zawahiri visited Iraq in 1998”

Does 2002 correlate with any other translated documents?
2002 seems very suspicious and that is one other reason I greatly suspect that the document is fake.
