Iran said today, Thursday, that three European countries have complied with the threats of "bullying student" Donald Trump when they activated the dispute settlement mechanism contained in a nuclear deal that the US President opposes, a move that could eventually lead to the re-imposition of United Nations sanctions on Tehran.

The nuclear agreement known as the joint comprehensive plan of action was concluded in 2015 between Tehran and world powers, and calls for the easing of sanctions imposed on Iran in exchange for reducing its nuclear program. Trump withdrew from the agreement in 2018, reimposed U.S. sanctions, and told Tehran he wanted an agreement imposing greater restrictions on the nuclear program and other things.

Iran has responded to US sanctions by cutting back its obligations under the agreement, which culminated in its announcement this month that it would abandon compliance with the restrictions imposed on its production of enriched uranium, but says it wants to keep the agreement.

Britain, France and Germany have activated the dispute settlement mechanism set out in the agreement this week. London said it was time to conclude a "Trump agreement", while Paris said broad-based talks should be held.

The Washington Post reported on Wednesday that the Trump administration had threatened to impose a tariff of 25 percent on imports of European cars if Britain, France and Germany did not formally accuse Iran of violating the nuclear deal.

"Appeasement has been confirmed. The three European countries have handed over the remainder of the agreement to avoid the new Trump fees. My friends will not succeed. You are just opening his appetite. Do you remember the bullying student in your high school?" .
