Help with training
Iraqi forces are being trained not only by the U.S. military, but by NATO and other nations inside Iraq. Canada, Germany, the Netherlands, and Jordan are helping train Iraqis outside the country. Naval patrol forces are being trained with help from Britain, Denmark, and Australia.
Iran would probably keep its reconstruction promises as well as Hezbollah in Lebanon, which made a big show of beginning rebuilding projects, and bailed out when everybody stopped looking.
