Payment for Services in Iraq

Can someone tell me why the United States is providing Iraq with its national defense and not seeking compensation for these services from the country’s sizable oil profits?

The United States has gone into deep debt to provide Iraq with a military police and with instructors to its own local defense mechanisms. At the same time, I understand Iraq is making many millions of dollars of profit each month from its oil sales.

Why isn’t some of that money going to pay back its debt to the United States for our major investment in Iraq’s national security? In effect, Iraq has outsourced its national defense to the United States, and not paid for it.

Our national debt has grown precipitously as a result, and our own local problems — schools, infrastructure — have suffered for lack of resources. Why not make the connection between these two phenomena?
