Any government that assumes power after the elections also realises this, so not even Sistani is going to call the US to withdraw its troops, despite what he is saying now, not until they are ensured the insurgency is out of the picture, or that they have an alternative foreign power (in this case Iran) to back them up.


"Results": [
    {
        "TypeName": "PER",
        "Text": "Sistani",
        "Start": 86,
