Iran's mullahs full of illusions about Biden

Iran will be one of the most important files in American foreign policy as a new president prepares to take over.

Outgoing President Donald Trump pulled out of the 2015 nuclear deal with Iran in May 2018. He re-imposed sanctions on Tehran.

Former president Barack Obama hammered out the deal with Iran in 2015.

Commenting on the presidential elections in the United States, Iranian supreme leader Ali Khamenei described the elections as a "satire".

He added on Twitter that these elections reflected what he called the ugly face of liberalism in the United States.

"Regardless of the results of the elections, one thing remains very clear: the political and moral decadence of the American system," Khamenei said.

United States Secretary of State Mike Pompeo reacted by accusing Khamenei of stealing hundreds of millions of dollars from his people.

"Your elections are a joke, with hundreds of candidates disqualified from even running," he wrote on Twitter.

"Today, your people starve because you spend billions on proxy wars to protect your kleptocracy," he added.

Observers said, meanwhile, that the collapse of the mullahs' regime in Iran would automatically spell the end of Shiite and Sunni political Islamist movements in the region.

The Islamic revolution of 1979, they said, blew new life into these movements which used to take a backseat in regional societies before the revolution.

The revolution opened the door for what some people describe as an "Islamist revival".

The failure and collapse of the Iranian model would reflect positively on the Middle East region, especially on predominantly Muslim countries.

Renowned writer Mohamed al-Sheikh said the Islamic jurist takes center stage in the Iranian system.

This jurist, he added, has absolute authority in this system.
