Steve Clemons at Washington Note has had some of the very best commentary about what's happening in Iran. Take a look at the four possible endings to the protests in Tehran.
One commenter adds this Langston Hughes poem:
What happens to a dream deferred?
Does it dry up
like a raisin in the sun?
Or fester like a sore--
And then run?
Does it stink like rotten meat?
Or crust and sugar over--
like a syrupy sweet?
Maybe it just sags
like a heavy load.
Or does it explode?
