Actually, from long time we heard that Obama will speak in an Islamic Nation, where he wants to send to Muslims around the world a message. I am Egyptian, and I was sure that it will be in Egypt, because Egypt is Islamic and Arab country, and we have one of the biggest Islamic organizations in the world Azhar, and may be the oldest one. Also Egypt is a very safe country.
But I don't care if Obama will give his speech in Egypt or Indonesia. The only thing that surprised me is that his speech will be in Cairo University (my university) and in the same place where Dr. Ahmed Zewail were giving a lecture in physics from about 5 years, and I was there. I am happy because I love my university :) and I wish it will return as a leader in education again.
