"[Suicide bombers in Iraq] don't need a lot of money. Suicide mission[s] at the moment are at rock-bottom prices. The cost is basically [the] cost of transportation from the border to the location of the attack plus the cost of the explosives. These people train themselves outside Iraq. Osama bin Laden actually calculated how expensive is the insurgency of Al Zarqawi. And it's only 200,000 euros, which is roughly $250,000 per week. The United States is spending $1 billion per week."
