The Europeans are looking like they might challenge US domination, breaking with the US over sanctions on Iran. From Middle East Monitor at theantimedia.com:
The Trump administration is apparently exasperated at the European Union’s bid to bypass US sanctions on Iran. Infuriated by the EU’s effort to save the Joint Comprehensive Plan of Action (JCPA) agreed in 2015 when Barack Obama was in the White House, Washington has threatened to punish any efforts seeking to circumvent the sanctions.
The US government is said to be putting the Europeans on notice, saying that if they try to bypass the sanctions on Iran, they will be subject to stiff fines and penalties. A senior Trump administration official who spoke on condition of anonymity about EU efforts to set up an alternative payment method to allow trade with the Iranians told the Associated Press that the US “will fully enforce its sanctions and hold individuals and entities accountable for undermining them.”
European leaders, however, are unfazed by the threats and are said to be marching forward with the plan, which, if implemented, could further strain trans-Atlantic relations. AP reported that a spokeswoman for EU foreign policy chief Federica Mogherini said that preparations for the alternative system are “at an advanced stage.”
