President Donald Trump is pulling the US out of the Iran nuclear deal and bringing back harsh economic sanctions. But it's how European governments and companies respond that may matter most.
The EU could use a "blocking regulation" to counteract US sanctions and allow trade to continue. "Not everyone in Europe, especially among European companies, is confident that [this rule would] allow the continuation of business with Iran," said Thomas Gratowski, an Iran expert at the advisory firm Global Counsel. "Its practical value is probably much lower than its symbolic value."
