Zarif made the remarks in an article he wrote in Le Monde, which the French paper published on Wednesday.

Through its obdurate campaign to bring about the total annihilation of the agreement, the United States is threatening to devastate what is left of multilateralism and international law, he wrote.

Known officially as the Joint Comprehensive Plan of Action (JCPOA), the agreement was concluded between the Islamic Republic of Iran and the P5+1 group of countries in Vienna in 2015, which at that time included the US, Britain, France, Russia, and China plus Germany, Press TV reported.

Zarif noted that the deal was made to address all concerns regarding “the exclusively peaceful nature of our nuclear program,” while freeing the Iranian people from inhumane and unjust sanctions.

In May 2018, however, US President Donald Trump unilaterally pulled his country out of the deal and later reimposed the sanctions that the deal had lifted. The US’s intransigence flew in the face of the fact that the accord has been ratified by the United Nations Security Council in the form of Resolution 2231.

Zarif said in his article that, as a result of US behavior, Iran has been the target of “the most vicious and indiscriminate sanctions.”

The US’s“inflexibility and unpredictability” have nothing to do with the precepts of “game theory,” in which players are expected to make rational decisions, Zarif said, adding that Washington is just after punishing any party which adheres to international law.

“Whether in the case of its domestic mismanagement of COVID-19, or the undermining of peace and stability abroad, the current administration in Washington has no real plans other than to blindly attack all those who defend the rule of law,” the article read.

The top diplomat concluded that with its current behavior, the US is just shying away from offering any prospect for the future of the global community, and warned that it is “neither desirable nor viable” to allow Washington a free hand in its actions.
