NBC news reported on Wednesday afternoon that multiple sources have told the network, President Donald Trump "is leaning toward decertifying the Iran nuclear deal".

Quoting four sources, including a "senior administration official, familiar with the White House deliberations", NBC says that Trump is thinking to decertify the deal before the October 15 deadline and leave and leave it to Congress to decide what to do.

In such a case, Congress will have 60 days to decide if nuclear related sanctions are to be reimposed on Iran.

The report says, that Trump's goal during that period is to try to get America's allies on board to push for renegotiating some provisions of the 2015 deal.

Britain, Germany and France closely worked with the U.S. to strengthen sanctions on Iran and force it to come to the negotiating table in 2013. Now, the issue is if they would agree to join the U.S. to pressure Iran back to the negotiating table.

On Wednesday, Trump told reporters that he has made a decision regarding the Iran deal, but did not reveal any specifics.

NBC quotes the "senior administration official' as saying that Trump has decided not to continue the "satus quo", but he's considering at least one other option.

That option is to lean on the Europeans, rather than pass the issue to Congress. According to the source, Trump will give 90 days to its allies to agree to reopen negotiations with Iran. The administration is in talks with the allies and with Congressional Republicans.

If Europeans agree to reopen talks and Iran refuses, the threat of another round of crippling sanctions becomes more real. U.S. sanctions alone will have a much limited impact than a coordinated and wide-ranging Western sanctions.
