Appeasement confirmed.

E3 sold out remnants of #JCPOA to avoid new Trump tariffs.

It won't work my friends. You only whet his appetite. Remember your high school bully?

If you want to sell your integrity, go ahead. But DO NOT assume high moral / legal ground.

Zarif said the countries “sold the remnants” of the Joint Comprehensive Action Plan (JCPOA), fearing the United States would impose new duties, noting that such actions only “whet the appetite” of US leader Donald Trump.

“If you want to sell your immunity, go ahead. But do not pretend high moral principles or legal grounds. You don’t have them, ”he stressed.

Earlier, Zarif said that Tehran “believes in diplomacy”, but is not going to change the JCPOA, as required by the United States.

On January 8, Trump announced that Russia, China and the European trio countries should withdraw from the JCPOA on the Iranian nuclear program, urging the parties to begin work on a new deal that will make the world more secure and peaceful.

Media later reported that British Prime Minister Boris Johnson allowed the replacement of the JCPOA on the Iranian nuclear program with the Trump deal.
