Iran’s supreme leader Ali Khamenei in Tehran in January played both sides of the divide all throughout the prolonged negotiations over the nuclear agreement, according to an article published in the New York Times on Jan. 19th.
While he cautiously welcomed on Tuesday the completion of the nuclear deal and the lifting of economic sanctions, he warned the government to guard vigilantly against what he called as "American treachery.”
Khamenei’s warnings seem to have been prompted in part by new United States sanctions over Iran’s missile program — announced less than 24 hours after the previous sanctions were lifted — and by remarks by conservative members of Congress.
“We must not neglect the deceit and the way oppressive regimes, especially America, break their promises, in this issue and other ones,” Khamenei warned in the letter.
“The comments made by some American politicians in the last two, three days are suspicious,” he wrote.
While praising the work of the negotiators, he frequently laid down “red lines” that seemed to reassure the hard-liners that Iran would not be bullied during the talks.
