Iran deal's fate may rest on late European interventions

The future of the landmark Iran nuclear deal hangs in the balance and its survival may depend on the unlikely success of last-minute European interventions with President Donald Trump.

French President Emmanuel Macron and German Chancellor Angela Merkel are visiting Washington separately later this month and, barring a sudden trip by British Prime Minister Theresa May, will likely be the last foreign leaders invested in the deal to see Trump ahead of his May 12 deadline for the accord to be strengthened. Trump has vowed to withdraw unless U.S., British, French and German negotiators agree to fix what he sees as serious flaws.

Those negotiators met for a fourth time last week and, according to U.S. officials, they made some progress but were unable to reach agreement on all points.
