Tasnim � Iranian Foreign Minister Mohammad Javad Zarif highlighted the massive efforts behind the 2015 nuclear deal known as the Joint Comprehensive Plan of Action (JCPOA) and said US President Donald Trump would �never get a better deal�.

�President Trump should've now realized that pageantries, photo-ops & flip-flops don�t make for serious diplomacy,� Zarif said on his Twitter account on Friday.

�It took 10yrs of posturing plus two years-literally thousands of hours-of negotiations to hammer out every word of the 150 page JCPOA. You'll never get a better deal,� he added in his tweet.

In May 2018, the US president pulled his country out of the JCPOA, the nuclear deal that was achieved in Vienna in 2015 after years of negotiations among Iran and the Group 5+1 (Russia, China, the US, Britain, France and Germany).

Trump on August 6 signed an executive order re-imposing many sanctions on Iran, three months after pulling out of the Iran nuclear deal.

He said the US policy is to levy �maximum economic pressure� on the country.

The second batch of US sanctions against the Islamic Republic took effect on November 4.

Following the US exit, Iran and the remaining parties launched talks to save the accord.

The European Union has vowed to counter Trump�s renewed sanctions on Iran, including by means of a new law to shield European companies from punitive measures.
