No one has a crystal ball that can predict what will happen in Iran, but I can tell you that from my perspective, I will never think of Iran in quite the same way.
So that's what Iran looks like? So the people there don't all want 'death to America'? So Al Queda is in fact our common enemy? So they are young, idealist, brave and desiring of peace and democracy? So one leader wasn't speaking for an entire people? I'll be.
I think that when we start scratching the surface we will find a whole lot more nations are not the propaganda cooked up by their government. In fact, see how rapidly most of the world has shifted its vision of us since we changed president.
And see how beautiful Islam is: these are details of mosques around the world i found on google image. (sorry no credit, I was sloppy. I'll see if I have time to hunt for these image's credit later on.)
Somewhere else
The point is: I'm glad I can toss some of my own fears and assumptions into a waste basket.
