The Arab enemies of Israel have been repeating for decades that Zionists wish to conquer the central Middle East, more specifically from the Nile River in Egypt to the Euphrates River in Iraq. I reviewed this subject in depth in 1994 in "Imperial Israel: The Nile-to-Euphrates Calumny" and will note here, in reverse chronological order, when it this conspiracy theory notably reappears.
2014: Again, Palestinian Media Watch report on this topic; now, Fatah spokesman Ahmad Assaf repeated the Nile-to-Euphrates libel twice in the same week, both times in Egypt. (March 23, 2014)
1997-2007: Itamar Marcus and Barbara Crook of Palestinian Media Watch at "From the Nile to the Euphrates - PA continuous libel (1997-2007) about secret plan to conquer Arab nation," which presents nearly two dozen instances of this theme in the Palestinian media over the past decade. (June 12, 2007)
