The "deal of the century" unveiled by President Donald Trump as a road map toward Israeli-Palestinian peace was met with furious criticism in Tehran.

Iran’s Foreign Minister Mohammad Javad Zarif called the plan a “dream project by a bankruptcy-ridden real estate developer” and a “nightmare” for the Middle East and the world.

At the international level, Trump’s “vision for peace” is seen as biased toward Israel. And, given the Palestinian rejection of the plan, it's believed it will have little chance of success. Given the Islamic Republic’s historic refusal to recognize Israel, and its unwavering support for the Palestinian cause, a unanimous condemnation from Tehran was no surprise.

Iran has been dismissive of Trump's plan, even when it was still in the pipeline. To signal that Iran's stance remains unchanged, the office of Supreme Leader Ayatollah Ali Khamenei reposted remarks he made in July 2018, when he called the plan a “devilish policy” that Muslim nations will never allow to materialize. Khamenei has, on different occasions, called the Middle East conflict the Islamic world’s top challenge. He has outlined his own version of peace, proposing a referendum that invites all Muslims, Jews and Christians living in occupied Palestine to decide their fate. Other Muslim states, however, have not yet welcomed the plan.
