ih rock

This has been bothering me for some time... How do you pronounce Iraq? Listening to NPR today two speakers used the word, one pronounced it IH-RACK, and the other, IH-ROCK. Various other pronounciations I have heard are

EYE-RACK
UH-ROCK
UH-RACK

From Wikipedia's Iraq entry you can hear what appears to be an authentic pronounciation. Although the sounds needed to say Iraq don't seem to be found in English, I would say it is somewhere between IH-ROCK and UH-ROCK, and nowhere near UH-RACK (or EYE-RACK for that matter).
