With that in mind, I've noticed that a recent statement from the USA government has announced that they've 'hit the wall' budgetarily in Iraq; they've given enough financial aid to rebuild Iraq. Apparently, they've concluded that almost $19 billion in handouts is quite sufficient, especially when half of it was engulfed by fighting the continued insurgency there and thus had no lasting effect as a basis for reconstruction. Instead, the Americans believe it's time for other governments to belly up to the bar and make their own contributions to the cause.
That's about as realistic as thinking that the new Iraqi Dinar will amount to anything of value in the near future.
Given that, should the USA ever leave Iraq, the country is as liable to devolve into a prolonged civil war as the former Yugoslavia was when an imposed authority --- Tito's Soviet-backed communist confederation --- inevitably fell away. That would be a strong indication that the prospects of a stable currency in Iraq are slimmer than the profile of a starving amoeba.
