Mohamed Bouazizi will be a person that should be remembered for some time. His self-immolation was the last straw for the people of Tunisia starting the revolution that has already overtaken two dictators in the Arab world. His contribution to history should never be forgotten.
While the revolts in the Arab world have yet to fully play out, the saber of the people has been rattled. Changes in the fabric of how the tyrants view their subjects has definitely shifted. The popular revolt is only one step towards change. Even governments not traditionally viewed as tyrannical have taken notice of the peoples' revolutions. While odds are good that the US has little to fear in a government take over, they have taken notice.
Mohamed Bouazizi should be remembered as a hero. In his act of defiance, he helped usher change in the world.
