In a series of tweets, the Islamic Republic foreign ministry officials have dismissed the U.S. Secretary of State's Mike Pompeo's remarks about returning the international sanctions on Iran.

Accusing Secretary Pompeo of "living in an imaginary parallel world," the spokesman for the Islamic Republic Foreign Ministry, Saeed Khatibzadeh, argued that since Washington is not a party to the Joint Comprehensive Plan of Action (JCPOA) or Tehran's 2015 nuclear deal with world powers, it cannot call for the snapback of the UN sanctions on Tehran.

After extending it for four times during the last two years of Barack Obama's and first two years of Donald Trump's presidency, the White House withdrew from the JCPOA in May 2018 and reimposed batches of devastating sanctions on the clergy-dominated Iran.

Pompeo reiterated on August 27 that the United States would make sure the UN international sanctions against Iran return on September 20.

Firing back sarcastically, Khatibzadeh maintained, "The hands of the clock only move in the imaginary parallel world of Pompeo."

The Islamic republic Foreign Minister, Mohammad Javad Zarif, for his part, dismissed recent threats of the United States for imposing sanctions against any country that stands against their snapback measures.

"After thrice being rejected by SC (United Nations Security Council), US now threatens sanctioning [sic] anyone and any entity that comes between US and its snapback," Zarif wrote in a tweet on Friday, August 28.

"Obviously they don't understand [the] law or UN. Maybe they can grasp this: You divorced the JCPOA in 2018. Your name on the marriage certificate is irrelevant," Zarif added.

Nonetheless, the U.S. still insists on being a party to the UNSCR 2231, if not the nuclear deal itself and has sent a letter to the UN Security Council to activate the snapback or trigger mechanism.
