Afghans, Crocker said, have "been there and done that. ... No one wants to go back to that." Instead, he said, major politicians from various ethnic groups want to have a voice in their nation's affairs — but not at the point of a gun. And, said Crocker, because the Taliban and its allies "are equal opportunity killers" who victimize all groups, they have "actually been a unifying factor" in Afghanistan.

That is where the actual quote is above is from. Second article is on a report that indicates that our nation building efforts are largely for naught since they will come to fruition too late and they are unsustainable by the Afghans.

the Special Inspector General for Afghanistan Reconstruction warned in a report released today that U.S.-funded construction projects now underway in Afghanistan that are costing hundreds of millions of dollars are behind schedule and may not be finished before U.S. combat forces depart. And that means, the report said, that the projects may not be "viable or sustained by the Afghan government after completion."

"Implementing projects that the Afghan government is unable to sustain may be counterproductive to the [counterinsurgency] strategy," the inspector general reported, as they raise Afghans' hopes for electricity and other basic necessities only to dash them later.
