I've created some word clouds from http://www.wordle.net/ from speeches given over the past days in the wake of the Iran election, as reported/translated on Andrew Sullivan's blog. I find word clouds to be an interesting way to pull out the themes. (I'll add a few obvious observations as well, to show what I took out of these. I know this smacks a little of reading palms or pop psychology; I'm offering these for the fun of it alone.)
Here is Mousavi's statement from yesterday.
In this case, the emphasis on revolution refers to the Islamic revolution --
I came to invite people to join the Islamic revolution in its honorable, original form, and to re-shape it into to what it must be
He is saying that this isn't a revolt, but a people's protest against something illicit.
Here is one from Khatami's statement today asking for a commission to look into the vote.
His emphasis is that he is responding to the people's will -- saying, 'I heard you.'
Here is President Obama's statement from June 20
His emphasis is on government and order more than human rights. He is saying that he is going to follow the rules of the international community.
In contrast, here is the House's resolution:
Their emphasis is on rights, freedom and liberty -- human rights over rule of law.
Here is Ayatollah Khamenei's speech from the prayer meeting on Friday.
He is emphasizing the process, saying the election process should be followed.
Here is the Grand Ayatollah Montazeri's statement -- he was part of the Islamic revolution, and, while very influential, is currently out of favor and has been under house arrest for a number of years. He called the current regime out, saying
a government not respecting the people’s vote has no religious or political legitimacy.
His emphasis is on the people -- he is emphasizing that these are not the terrorists that others are claiming, but our youth and children.
Oddly enough, I couldn't find a good statement or speech to use from Ahmadinejad. If anyone has one, I'll be happy to add it.
