Bush was probably unaware and a little naieve of the depravity of Islam and much of the radical element. Obummer - He has to know the evil and depraved tendencies of Islam and is empowering them with weapons so they can declare caliphates. BIG difference. We have an enemy of the state under our own noses in the WH and they can’t even see it.
There is a difference in WHY, but not in what. The result? Bush publicly insisted this “religion of peace” flapdoodle…..often. His administration is still part of 13 years (post 9-11) where America will NOT admit, at the highest levels of the government, who and what we are fighting.
