Iran’s Supreme Leader Ayatollah Ali Khamenei unleashed a barrage of sharp criticism against the Emirati government over its normalizing relations with Israel, saying, “The UAE committed treason against the Islamic world, the regional nations and Palestine.” Khamenei expressed confidence that the agreement itself “will not last long” but will stay forever as “a mark of disgrace” for Emirati authorities.

The stinging rebuke was the Iranian supreme leader’s first public reaction to the agreement, which calls on Tel Aviv to halt its controversial annexation of large swaths of territory in the West Bank, allowing for Emirati-Israeli cooperation in multiple economic and security arenas. The American-brokered deal made the UAE the third Arab country, after Egypt and Jordan, to enter formal relations with the Jewish state. The Emirati government’s decision has already drawn the ire of several Palestinian groups and Muslim states, including Turkey, which criticized it as “unforgivable” and “hypocritical.”

Khamenei’s speech, which was delivered as a virtual address to Education Ministry managers, appeared also as a warning to other Arab nations not to follow suit. He noted that the deal will pave the way for Israeli influence in the region and is meant to “throw into oblivion the Palestinian question,” which is about “a country being usurped” by Israel.

But that’s not where the criticism ended. The Islamic Republic’s leader took aim at the United States for facilitating the agreement. He made a pejorative reference to Jared Kushner — the son-in-law of US President Donald Trump — known for his close ties with Israeli officials. According to Khamenei, the UAE decided to cooperate with Israel and “dirty elements in the United States, including the Jew in the Trump family … who all act against the interests of the Islamic world.” Khamenei, however, expressed hope that “Emirati officials will soon wake up and make up for what they have done.”
