"We'll need a great network of informants"
That would be a tricky one...
In a tribal environment ?
How do you get them?
Paying them ? the neighbours would become suspicious if one of them suddenly dress his children better or looks better fed than the rest... And they know what would happen to them and their family if the neighbours find it out...
Fear ? that means to make them fear more the US than the iraqi terrorists... that would mean beheadings and burning people alive... But we already seen what happens if some interrogations gets a bit tough...
Israelis know how to cultivate informants in the Paleostinian areas. We should learn from them though it's a difficult process. Israelis have many Jews who came from Arab countries who can blend in with Arabs. They look like Arabs. Our situation is different.
