This is why it says in Bereshit 36:31-39 that eight kings of Edom rule before the rulership of a king, Moshiach, over Israel. The Arizal explains that the first seven kings represent the Klipot that must be clarified. That is, the Kedusha in them must be removed from the Tum'a in them, to render them powerless.
It seems to me that the 64 years from 5708 to 5772 represent the final eight kings of Edom in the dimension of time. Each Edomite king rules for eight years. After seven kings, in 5764, Edom used his last power within Israel to launch the "disengagement." He remains exposed, without merit, with no more power over the Land of Israel.
After the eight kings, the Torah mentions eleven Edomite chiefs. I think this means that the fall of Edom takes time, 11 years, eleven being the difference between the regular lunar year and the solar year. This may shed light on what I wrote earlier about the years 5772, 5775, and 5783.
