Iran's top negotiator Mohammad Bagher Ghalibaf issued a stark warning to the United States on Monday, demanding acceptance of Iran's new 14-point proposal or threatening that American taxpayers "will pay for it." Speaking publicly about the ongoing negotiations, Ghalibaf stated there is "no alternative but to accept the rights of the Iranian people as laid out in the 14-point proposal."

The ultimatum comes as tensions between Washington and Tehran remain elevated, with former House Speaker Newt Gingrich describing the situation as presenting President Trump with a "very difficult choice" when he returns from China. Speaking on Fox News' "Outnumbered" program, Gingrich emphasized the high stakes surrounding the current state of U.S.-Iran negotiations.

Complicating the diplomatic landscape, Senator Lindsey Graham called for a "complete reevaluation" of Pakistan's role as a mediator in the peace talks following reports of Pakistani cooperation with Iran. CBS News reported that Pakistan has allegedly allowed Iranian military aircraft to use Pakistani airfields, including Air Force Base Nur Khan.

The developments highlight the complex web of regional alliances and the challenges facing U.S. policymakers as they navigate diplomatic relations with Iran. The specific details of Iran's 14-point proposal have not been made public, and it remains unclear what timeline Iran has set for a U.S. response to its demands.
