So it took Greece about 10 days after the election to get to the riot stage.
The lesson I see is that we may have this much or less time if we face a similar situation.
I can think of a few things that might drive Americans to the riot stage.
Current events, here, seem to point at next year's elections, but there are other political factors
that are also getting some media attention.
I'm of the opinion that a social breakdown will happen quickly, rather than a gradual slide. Of course, we've been in a slow downward slide for literally years.
Look at the past events which led to riots in single cities. If we reach the point of effecting multiple cities, that is a major warning sign.
All quiet on the front, sir. But the natives are restless tonight.
