A lot of questions into the actual effectiveness of these sanctions.

The economic impact of U.S. sanctions against Iran is unclear and Iran has signed about $20 billion in energy contracts with foreign firms since 2003, said a U.S. audit report.

“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.

It looks like other countries don’t need the U.S. like they used to.
