Edom Before Hatzot, Yishmael Before Minha Gedola
Edom had their revolutions before Hatzot Hayom (12:00 noon) of the cosmic clock.
Yishmael is in the midst of their revolutions before Minha Gedola (12:30 PM) of the cosmic clock.
A possible explanation:
Edom is Eisav, who rivals Yaakov Avinu. Yaakov Avinu instituted Arvit, the evening prayer. Its power is at Hatzot Halaila (midnight). Edom became less extreme via their revolution, and they no longer wanted to confront Yaakov Avinu head-on as in the past. They therefore had their revolutions before Hatzot Hayom, which is the furthest you can get from Yaakov Avinu's power.
Yishmael, on the other hand, rivals Yitzhak Avinu. Yitzhak Avinu instituted Minha, the afternoon prayer. The earliest time one may pray Minha is at Minha Gedola (12:30 PM on an equinox day). The revolutions in the Arab world, from the looks of it, are making them more extreme, and they want to confront Yitzhak Avinu head-on more than in the past (see here).
May Hashem save us from both Edom's decreasing extremism and Yishmael's increasing extremism.
