Iran
Holy crap.
This is obviously going to very ugly before it resolves.
I was just becoming aware of world events (thanks to my paper route!) in 1979 when the Iranian Revolution took place. I remember being riveted by the hostage crisis and the surrounding events. As with many "movements" that are tied to a specific generation, there is often tension as the younger generations become the political majority. It would not shock me if we are seeing a last gasp (a la Orange Revolution). Nor would it shock me if, instead, this is the event that solidifies a dictatorship (a la Tienanmen Square).
