Afghan government officials were forced to scrap a costly training facility built on the Pentagon’s dime after its walls “melted” and the site became too dangerous to use.
The Special Inspector General for Afghanistan Reconstruction had unusually harsh words for the failed project, calling it “not only an embarrassment” but “a waste of U.S. taxpayers’ money,” given the fact that Afghans had to tear down the Defense Department contractors’ work and rebuild it themselves.
