Iran's Ahmadinejad sees no threat from US

Iranian conservative cleric Ebrahim Raisi representing the Popular Front of Islamic Revolution Forces (JAMNA) has registered to run in the presidential election due on May 19, the ISNA news agency reports.

"Those who made incessant efforts on the nuclear pact should tread the path up to the end", he said in remarks to the press after registering as a candidate.

Ebrahim Raisi, 56, a hard-line cleric close to Iranian Supreme Leader Ayatollah Ali Khamenei, on April 14 filed to run and is considered by many to be the 68-year-old Rohani's main challenger.

"He has no experience in foreign policy, so at least initially he will have to follow the system's grand strategy of preserving the nuclear deal and shifting any blame of undermining it to the U.S.", said International Crisis Group Iran analyst Ali Vaez.

"I have come to be the candidate for all of Iran".

Many wonder why he would risk a run for the presidency if, as speculated, he is being considered as a possible future supreme leader.

The presidency could provide a stepping stone to the top - as it was for Khamenei in the 1980s. The applicants will then be vetted by the Guardian Council, a clerical body that will announce a final list of candidates by April 27.

"The strengthening of the capability of the Iranian armed forces.is only for defending the country and we will ask no one's permission to build up the armed forces, and to build missiles and aircraft", he said at a televised event showcasing some locally built military hardware, according to Reuters. "We have to gather again for Islam, to build Iran together". Many Iranians joke they have already experienced their version of Donald Trump.

Earlier on Wednesday, Iran's former president Mahmoud Ahmadinejad had registered for the upcoming Iranian presidential election.

Baghaie, 48, was vice-president for executive affairs and headed the tourism board under Ahmadinejad.

"Those who sympathise with the heads of sedition must know that the great nation of Iran will never forgive this great injustice".

Other well-known applicants who registered on Friday include lawmakers Hassan Norouzi and Mostafa Kavakebian, former parliamentarian Alireza Zakani, reformist figure Mohammad Zare' Foumani, pro-government politician Amrollah Sheikhiaei, and prominent theological teacher Ayatollah Mohsen Gharavian.

A war veteran, former Revolutionary Guards commander and police chief, he is a staunch conservative. Some say his campaign will be damaged by an ongoing real estate scandal in his municipality, but he has experience and powerful backers.
