The United States next?

I'm editing the Landmark History of the American People by Daniel Boorstin for an elementary school age audience. I am in the midst of the section dealing with the U.S.' Declaration of Independence. I needed to check a particular phrase . . . and wound up at http://www.livestream.com/globalrevolution. I have not been following Occupy Wall Street. And we don't have television, so I have never seen any of this kind of coverage before.

In the context of my American history studies and the Arab Spring revolutions, it struck me, watching the live feed: This is how governments fall. Is the U.S. next?
