Not only has Cairo seen its government and constitution disbanded, its military take over to form a (hopefully) temporary military state, but now there are demonstrations in Iran, too. Hundreds of thousands of demonstrators marched in Tehran to show support for the Egypt uprisings and have clashed with the military. The difference in Iran, however, is that the military is under the control of Ahmadinejad and the control of the people is vastly stronger than it was in Egypt. Already, it seems as though the people of Iran are being beaten back by overpowered, well-equipped soldiers in the streets.
But there's more. There are protests happening all over the place: Yemen, Sudan, Jordan, Algeria, Bahrain, and Tunisia. People all over the region are rioting and protesting the control of overbearing regimes, dictators, and authoritarian governments. This might not be very out of place for these countries, but having so many protests and demonstrations so close together, and having some of them be so effective, shows that the people are tired of being trampled by their government and leaders and have found something to bring them hope.
As I've said in older posts, these demonstrations are a step towards Democracy. They are a crucial, bloody, and difficult step, but one that is necessary in order to create lasting peace. The American Revolution was similar in the sense that the colonists revolted in order to overthrow a stifling power that limited their rights and stripped them of their dignity and hope. We are seeing similar uprisings in these countries for similar reasons: the people being tired of oppression for the power and benefit of their oppressors.
Whether these new protests and demonstrations will result in eventual stability and freedom or continued oppression, we can't yet see. It may be that these demonstrations will come to nothing, but they could be the start of great moves toward liberty in the region. Fingers crossed.
