Egypt's Mubarak faces toughest challenge yet
By Matt Smith, CNN
(CNN) -- For nearly 30 years, one man has dominated Egypt.
Hosni Mubarak, 82, has survived would-be assassins and ill health, crushed a rising Islamist radical movement and maintained the peace with neighboring Israel that got his predecessor killed. His government's continued observance of the Camp David accords with Israel is the cornerstone of what peace has been achieved in the decades-long Arab-Israeli conflict.
Following the revolt that toppled Tunisia's longtime strongman, demonstrators in the streets of Cairo are standing up to riot police and chanting, "Mubarak, Saudi Arabia is waiting for you." Experienced observers say it's the most most significant challenge to his rule yet.
