Revolution are also peaceful. What took place in Eastern Europe is proof of that.
Well, we can look at the entire history of our country as being one long, slow revolution, but I'm not sure that that's what is being meant by revolution in this article.

What do most people mean by revolution in the context of the USA? Not much, I suspect.
