I see this article by The Telegraph about alleged American involvement in the uprisings and rebellions in Cairo, Egypt, and I think to myself, "This isn't the first time..."
Sadly, the United States has backed rebellious groups in countries, particularly Iran, to overthrow or undermine the government. So, these accusations aren't all that surprising. I think the United States needs to stop trying to install democratic governments across the globe - you can't force people to do what you want and have happy nations. The United States is a protector and support of democracies; this does not mean we have the right to go to other countries and impose our ideals and beliefs on them because we believe that democracy is the only way to go. This just makes our relations with the international community that much more tense and difficult.
