I know one of the aftermaths of this war is the hope that American style democracy spreads throughout the middle east.
Right now if you hold elections in Pakistan, Iraq, West Bank/Gaza Strip, Egypt, Saudi Arabia and some other countries; the people will vote for a radicial Islamic government.
The irony- the country that people are using as the basis for that: Iran; the people there would probably vote for American style free democracy and seperation of religion and government.
What will really change the middle east is some resolution to the Israeli-Palestinian conflict and seeing the Iranian people overthrow an radical Islamic government that many of the Arab people want. Since Iranians have lived under this regime for 24 years; they see it isn't working.
