US aid to Afghanistan

"By the broadest measure of accounting for the costs of the effort, the United States has spent $90 billion on aid and reconstruction in Afghanistan since 2002, a figure that includes programs run by the United States military and the costs of providing security for the effort, according to Mr. Sopko’s agency, the Special Inspector General for Afghanistan Reconstruction.

By the narrowest measure — money funneled through U.S.A.I.D., the State Department agency that has taken the lead in the civilian aid program — the total is $15 billion since 2002."  So it is $15 out of the total $90.
