“And how has Obama’s obsession of Assad played a role?”
Don’t forget that Obama and the rest of the DC gang fomented the “Arab Spring” with close cooperation between the CIA and the Muslim Brotherhood and the advent of ISIS.
And it isn’t a coincidence that the Arab Spring has happened in the Arab countries that surround Israel.
Israel is the ultimate target that Obama and the DC gang want to wipe off the map before the world government comes to power.
While I agree with your other points, I must say that the Arab spring, with the exception of Syria and Egypt did not happen in the ARab countries that srround Israel — Jordan, Lebanon and Saudi Arabia did not get this. And the big changes for the Arab spring - Tunisia, Libya and yemen are not particularly close to Israel
