TEHRAN (Press Shia) – An Iranian cleric slammed the US president’s harsh remarks against Iran at the UN General Assembly as an indication of Washington’s outrage at its “ideological failures”, noting that Russia’s alliance with Iran in the war against terrorism has infuriated and frustrated Americans.

The anti-Iran remarks at the UN General Assembly were made by a weak-minded, hawkish, and lying person who is the US president, Tehran's Provisional Friday Prayers Leader Ayatollah Kazem Seddiqi said in a gathering of worshippers.

Highlighting Donald Trump’s plummeting popularity in the US, the cleric said a person without domestic support would get easily irritated.

He also attributed the US administration’s anger to its ideological defeats, adding, “Russia’s leader stood with us in the war against Daesh (ISIL terrorist group) which has resulted in the US frustration and fury.”

In comments on Thursday, Leader of the Islamic Revolution Ayatollah Seyed Ali Khamenei deplored recent remarks by Trump against Iran as “foolish, very ugly and ignoble”, saying they were rooted in Washington’s anger over its defeats in West Asia.

“The foolish, very ugly, and ignoble speech of the US president, with its gangster and cowboy language full of sheer lies, is rooted in their anger, frustration, and light-headedness,” Ayatollah Khamenei said in a meeting with members of Iran’s Assembly of Experts.

The remarks did not stem from power but from anger and frustration because the Americans are infuriated that their years-long plots in West Asia have been foiled following the Islamic Republic’s effective presence in the region, the Leader stated.
