'Great': US envoy answers Iran's top diplomat in cryptic, deleted post

US President Donald Trump's special envoy Steve Witkoff reacted "great" to a spirited statement by Iran's foreign minister on X before swiftly deleting the post.

Foreign Minister Abbas Araghchi had written four paragraphs lamenting Washington's exit from a nuclear deal and recent talk of attacking Iran.

"10 years after signing the JCPOA—and 7 years after the US unilaterally walked away from it—there is not ONE SHRED OF PROOF that Iran has violated this commitment," Araghchi wrote, referring to a 2015 agreement from which the United States withdrew in Trump's first term.

"Diplomatic engagement worked in the past and can still work. BUT, it should be clear to all that there is—by definition—no such thing as a 'military option' let alone a 'military solution'," he added.

Witkoff, who has spearheaded talks for Trump in Israel-Hamas and Ukraine-Russia conflicts as part of the populist President's bid to wind down foreign reports, replied simply: "Great".

It was not immediately clear if the expunged monosyllable, which marks the first public interaction between Tehran and the Trump administration, was meant in earnest, irony or error.
