It was with great regret that I learned of the passing of Crown Prince Sultan bin Abd al-Aziz of Saudi Arabia. As Minister of Defense and Aviation for almost 50 years, Crown Prince Sultan dedicated himself to the welfare and security of his people and country and was a valued friend of the United States. He was a strong supporter of the deep and enduring partnership between our two countries forged almost seven decades ago in the historic meeting between President Roosevelt and King Abd al-Aziz Al Saud. On behalf of the American people, I extend my deepest condolences to King Abdallah, the royal family, and the people of Saudi Arabia.
