I have no idea why I am posting on here, but must admit I have been watching this situation for the last week and am somewhat inspired. Also, as much as I hate to admit it, this was what George Bush some what envisioned: Democracy taking hold in the middle east. Though Bush's ignorance of history would have told him that the US has toppled democratic governments in the past in favor of economic allies (yeah rip me for that one).
First off to watch this take place organically is fascinating to watch. Whether or not you like social networking sites, their power in these revolutions is amazing to watch (side note to my teacher friends a lesson of students writing tweets for the American revolution would be really good).
Second, who takes charge and what support do they receive from the US. If Elbaradi (may have spelled that wrong) takes power he will have international support and given his peace credentials I doubt he would make any move against Israel. Though there seems to be no real leader, and this does not seem to be driven by radical clerics. However, a repressed youth and struggling economy are breeding grounds for Islamic extremeists so you never know.
If the real desire of these movements is for more people to be involved in the government and open access to education, work, women's rights, and the such than the US should support every effort. There have been some protests in Yemen, and if Egypt does fall that fire will only spread to that country next. A small protest was quickly put down in Saudi Arabia, but it could catch fire after Yemen. Though that will be the hardest place to take over.
There is a final note though that Americans should think about. Many of these protesters are upset about the consilidation of wealth from oil. Could US oil prices jump from new leaders hoping to increase their profits to fund their new governments and projects? How will the state department respond then? How will you?
