Arab-born German citizen, Nasim Ben Iman wrote a book “Der Wahre Feind” (The True Enemy) and has been an outspoken apostate (former Muslim) risking his life to warn the western world of the long range dangers of fundamentalist Islam.
He states the rapid progress of Islamic conquest would not be possible if not for naivety of western cultures that refuse to see the obvious, claiming we are “asleep” while the growth of radicalism marches on. He also talks about the mosques, how public statements by Muslims in Germany are completely opposite than what is preached inside. This is worth the ten minutes, with English translation.
