The agreement with Tehran "represents the same failure of the past that led us to the emergence of the current threat from North Korea", said the head of the U.S. Department of state.
He also noted that this document does not take into account a number of other threats posed by Iran, therefore the US, according to him, carefully studying all aspects of the policy of Iran and the results of the analysis will take appropriate decisions.
Rex Tillerson accused the government of Iran in fuelling numerous conflicts, in undermining the US interests in Syria, Yemen, Iraq and Lebanon, and to support attacks against Israel.
Just a few days earlier US Secretary of state in a letter to the speaker of the house of representatives, Paul Ryan confirmed that Tehran adheres to the agreement on the nuclear program. At the same time, he stressed that Iran remains one of the main state sponsors of terrorism.
