Egypt imports over two billion dollars in US aid annually but apparently has exported the bulk of the foreign jihadists in Iraq. Syria's the number two exporter and, despite repeated US warnings going back to 2003, remains the "main passageway for suicide bombers in Iraq." From the Gulf Times:
The US military said yesterday that it has several hundred foreign fighters in custody in Iraq and that most of them come from Egypt, followed by Syria, Sudan and Saudi Arabia. "We have several hundred foreign fighters in captivity at this point of time and the greatest number come out of Egypt," spokesman Major General William Caldwell told reporters.
