This speech of Obama show’s once and for all he is probably a Muslim and will not hesitate to speak the biggest lies. ...there was no Muslim contribution to the building of American....only attempts at destruction.
Cultures created by and founded on Islam are by necessity “parasitic” cultures...they are indoctrinated to get the goods of life by theft, conquest and violence. This is especially true of Arabic cultures found in the Arabian peninsula, that were the incubator for Islam.
Only the advanced cultures they conquered or tried to conquer have produced advancements. Such as India, Pakistan, Egypt, some African cultures, Spain, Turkey.
If their leaders don’t change soon, most of Europe will be added to the “host” cultures.
The Turks are an interesting case.
They had a few centuries of dominance in the eastern Mediterranean and the Balkans, but they were mainly adopters of western methods (the Byzantine administrative system, cannons) rather than innovators, and most of their history is one of decline after their big conquests.
They were rejuvenated by the secularization under Ataturk, but that’s receding now as Islam makes a comeback.
