Zarqawi's Death at 2/3 Mark of War?
Abu Musab al-Zarqawi (ימ"ש) was killed by U.S. Forces on June 8, 2006.
The U.S. invaded Afghanistan on October 7, 2001 (Hoshana Rabba, 5762 - it was October 8th in U.S. time).
The difference is 4-2/3 years.
4-2/3 years is exactly two-thirds of 7 years.
According to some (see here under the heading "War of Gog Umagog" and also mentioned in Arutz Sheva), the war of Gog Umagog started when the U.S. invaded Afghanistan, and is supposed to last 7 years.
What the significance is is not clear. It's just an interesting thought.
