Hmm. Sanctions don’t work?

The G.A.O. reports[*1] (via Yahoo News):

“U.S. officials and experts report that U.S. sanctions have specific impacts on Iran; however, the extent of such impacts is difficult to determine,” said the report by the nonpartisan Government Accountability Office, which was obtained by Reuters late on Tuesday.

“Other evidence raises questions about the extent of reported economic impacts,” it added.

The report by the investigative arm of Congress comes as the Bush administration is pushing for a third round of U.N Security Council sanctions against Iran and planned talks with major powers in Berlin next week to iron out differences on those punitive measures.

Hmm.  So . . . sanctions would have worked with Iraq if only they’d been given more time, but sanctions are of questionable utility against Iran.  Anybody having trouble following the “narrative” here?
