Regarding the US and Britain's "spoils" of Iraq. There seems to be the presumption that the "economic benefits", derived by the citizens of the individual countries involved in Iraq's "reconstruction", will somehow outweigh the cost to individual taxpayers for upgrading and maintaining the armed forces required to "keep the peace" there.

I'm not sure I have that much faith in the trickle down economics. What other carrots are the US and Britain willing to hold out for Canada and other UN members' participation in the costly clean up of this non UN sanctioned mess?
