Obama allowed for the MB take-over of Egypt because the alternative was telling the army to massacre the people in Tahrir Square.
Allowing for the fall of Mubarek, elections, and trying to work with the MB (while maintaining relations with the army) was seen as the best way to manage the situation. Sure enough, the army coup’d the Brothers, putting Egypt right back to square one.
As for Libya, it provided a welcome distraction from all the US-backed regimes under threat at the time (especially Yemen and Bahrain) since Ghadaffi was deemed more expendable than the other two, and had a small, weak regime (even then it took 6 months for the rebels to win even with air support).
Al Qaeda is more strong and present in Syria than anywhere else in the world right now, and there is NO reason for the US to support the Islamists in Syria other than to weaken Iran and Hezbollah. No reason at all.
Unless you understood that Obama if fulfilling an Islamic prophecy in engendering what Islamists understand as a ‘John-The -Baptist’ forerunner to the Mahdi or 12th Imam.
He is almost single-handedly attempting to restore the Ottoman empire in the North - and a Sunni Arab Caliphate in the South at the same time.
The ONLY strategy Obama applies, is whatever hurts America and aids Jihadists.
Period. Obama STARTED the Arab Spring protests in Egypt, Libya and elsewhere.
