Alexander was an internationalist in the widest sense. Unlike his father, Alexander was curious about the foreign cultures, especially in Asia, that he came into contact with. He enjoyed enthnography and assimilated many of the cultures, such as the Persians, into his own, much to the chagrin of the Macedonians. Remember, he was tutored as a youngster by Aristotle and took Aristotle's nephew, Callisthenes, along as his biographer. In many ways, Alexander was a leader without blemish; his men would do anything for him which they proved over nearly a decade of hard marching and conquest. But it was his insistence on pushing further and further East and his fascination and appreciation of Asian cultures that led to a mutiny outside of India. He also took a foreign wife, Roxanne, much to his men's displeasure. I would recommend you read Peter Green or Robin Lane Fox's description of Alexander's program of acculturation and how he favored many key personages, such as Bagoas, more than his own men.
