Jeez, Rome wasn't built in a day.
Give this thing some time to gel for crying out loud.
At least the fractious Iraqis (long divided by sectarian and ethnic groups) have a shot at sorting things out for themselves in a reasonable manner. They as a people will be better off in the long run than under the clutches of a lunatic dictator like Saddam Hussein.
Europe, for all its pissiness, will start contributing for long-term economic development (as it had in the past). Right now we and the Iraqis need to mop up the remaining "insurgents" (mostly remnants of Saddam's regime) and get the country's infrastructure back together. At the same time Iraq has to get its main export business stabilized. And so on.
Economic fermentation almost always leads to social fermentation (liberalization in the classic sense). This is happening in countries like the United Arab Emirates, and is eventually bound to happen in places like Saudi Arabia and even Iran, which has a burgeoning liberal middle class.
Like or not, the ouster of Saddam is a long-term investment (which cost American $$$ and yes blood), the return on which is measured in DECADES.
You can't expect miraculous results overnight.
p.s. Combine stabilization of Iraq with improved prospects for peace in Israel/Palestine, and you have a much more optimistic future in the Middle East. It will take time, but gradually Arab terrorists will continue to be marginalized.
