The national unity government will need to implement a program that brings all Iraqis together, builds a happy future for the people of Iraq, and gets Iraq to stand on its own feet.

The feeling of being an Iraqi unites all ethnic groups within this country. Even the Kurds, who have traditionally pushed for their own state, see the benefits of the current situation. They enjoy an autonomous status in Kurdistan, while at the same time participating in decisions in Baghdad. But if neighboring states were to push for a partition of Iraq, it would be a horrible mistake.

Americans have eliminated Iran's worst enemies, the Taliban in Afghanistan and Saddam [Hussein]. I occasionally threatened my Iranian counterpart in Kabul that one day I would send him a big bill for what we did. But, seriously, Iran is pursuing a dual strategy in Iraq. On the one hand, the Iranians, after decades of hostility, are now interested in good relations. On the other hand, they want to keep the country weak and dominate the region.

We're dealing with such enormous problems today that we have no other choice but to work together. If Iraq fails, if a religious civil war breaks out and the neighboring states are drawn into this conflict, if the Kurds declare independence and al-Qaida takes over an entire province - that's when the consequences will be dramatic.

I constantly signal to the Iraqi leaders that our patience, or the patience of the American people, is running out.

Nation building is our central task, both in Afghanistan and in Iraq. And states, nations can't just be built with military power. Despite all difficulties, it's very inspiring to see how the Kurds, the Arab Sunnis and the Shiites are coming together here, how they're jointly defining the basis on which their state is to be built, the political course this state will pursue and who is to receive which cabinet positions.

The U.S. and Iraq will work together next year to shift Iraqi resources from unproductive subsidies to productive uses that enable Iraqis to earn livelihoods.
