<p>The $100 billion Iraqi Oil for Food program was by far the largest relief operation in the history of the United Nations. By extension, it's rapidly becoming the U.N.'s largest-ever scandal.</p>
<p>After months of stonewalling, Secretary General Kofi Annan conceded Tuesday that the program was worthy of an internal investigation. It's a step forward, but it's not nearly enough for an organization that so far has shown it can't be trusted to police itself. That's why the April hearings by Henry Hyde's House Committee on International Relations will be so important. Oil for Food is a legitimate U.S. concern, for reasons that go well beyond the fact that U.S. taxpayers foot about a quarter of the U.N.'s bills.</p>
