You want to go to Iraq, join the military. You'll get there in a hurry. I can't imaging anyone wanting to risk their lives for money they may not ever live long enough to spend.
Sorry, just my opinion. My son was there for 8 months on his Marine rotation, becuase it's his job, but I can't imaging anyone wanting to VOLUNTARILY be there considering the current circumstances, no matter how much they are paying. What is your life worth?
