From the Summary: "Historically, Egypt has been an important country for U.S. national security interests based on its geography, demography, and diplomatic posture. Egypt controls the Suez Canal, which is one of the world's most well-known maritime chokepoints, linking the Mediterranean and Red Seas. Egypt's population of more than 100 million people makes it by far the most populous Arabic-speaking country. Although today it may not play the same type of leading political or military role in the Arab world as it has in the past, Egypt may retain some 'soft power' by virtue of its history, media, and culture. Cairo hosts both the 22-member Arab League and Al Azhar University, which claims to be the oldest continuously operating university in the world and has symbolic importance as a leading source of Islamic scholarship."
