Iran Sanctions

In an unexpected reversal, President Barack Obama declined to sign a renewal of sanctions against Iran but let it become law anyway, in an apparent bid to alleviate Tehran's concerns that the U.S. is backsliding on the nuclear deal.

Although the White House had said that Obama was expected to sign the 10-year-renewal, the midnight deadline came and went Thursday with no approval from the president. White House press secretary Josh Earnest said Obama had decided to let it become law without his signature.

Though Obama's move doesn't prevent the sanctions renewal from entering force, it marked a symbolic attempt by the president to demonstrate disapproval for lawmakers' actions. The White House has argued that the renewal is unnecessary because the administration retains other authorities to punish Iran, if necessary, and has expressed concern that the renewal may undermine the nuclear deal.

So, no veto?

Fine, I expect Iran will take note, seeing as how they just claimed the US is in violation of the nuclear agreement.

"Extension of the Iran Sanctions Act does not affect in any way the scope of the sanctions relief Iran is receiving under the deal or the ability of companies to do business in Iran consistent with the JCPOA," Kerry said, using an acronym for the nuclear deal.

But, symbolically?

...but hey, do what you want...you will anyway.
