I have reached this research conclusion: the first Arab critique of the US was contained in a speech that socialist Arab thinker, Farah Antun, gave near Niagara falls in upstate New York early in the 20th century (around 1907). It has the first Arab treatment of the mistreatment of Native Americans. Egyptian writer, Abbad Mahmud `Aqqad, said that Antun could be declared a great writer for only this speech of his. Read it.
