Now, we plan to unlock billions of dollars and lift sanctions, with the promise of even more money.”Trump’s plan has drawn unfavourable comparisons to former US President Barack Obama’s more detailed 2015 agreement with Iran, under which Tehran agreed to limits on its nuclear programme in exchange for sanctions relief.Trump pulled out of the deal in 2018, saying it had “enriched the Iranian regime and enabled its malign behaviour”.Mike Pence, who served as Trump’s first vice president, said on Wednesday that the US-Iran MoU “does smack of the kind of appeasement that our administration rejected in the Obama-Iran nuclear deal”.Pence said the US should pursue an agreement that “commits Iran to dismantling their nuclear programme, dismantling this missile programme, ends support for terrorist proxies and opens the strait”.“Failing that, we should let our Armed Forces finish the job on our terms,” Pence said on X.Senator Ted Cruz of Texas defended the MoU from comparisons with the Obama deal, but expressed concern about providing funds to Iran.“I do want to urge the president not to give up the victory; we have destroyed their military, and we should not fund the rebuild,” Cruz said on X.
