FNA - Top Military Aide to the Iranian Supreme Leader Major General Yahya Rahim Safavi said US President Donald Trump is leading his country towards fall due to his unwise decisions and policies.

"Unwise leaders will bring humiliation for nations and therefore, certainly the US will go towards decline for having an unwise president and it will be defeated against the power of our country and the resistance front," General Rahim Safavi said, addressing a ceremony in the Northern city of Qazvin on Sunday.

Elsewhere, he downplayed impacts of the US sanctions against Iran, and said the Iranian nation is undefeatable.

"But the enemies of Iran will be defeated and the US will be soon forced to leave West Asia, Syria, Iraq, Afghanistan and the Persian Gulf to escape (ultimate) failure."

In relevant remarks on Saturday, Iranian Foreign Minister Mohammad Javad Zarif ensured that his country would survive the US sanctions and thrive despite pressures and threats by Washington.

The Iranian diplomatic chief made the remarks in a post on his Twitter page, dismissing his American counterpart's starvation threat, and stressing that the Islamic Republic would survive and even advance despite Washington�s sanctions

The top diplomat described Pompeo's open threat to starve the Iranian nation as "a crime against humanity" and "a desperate attempt to impose US whims on Iran".

"Like his predecessors, he'll also learn that�in spite of US efforts�Iran will not just survive but advance w/out sacrificing its sovereignty," Zarif said.

Zarif's tweet came after the US Secretary of State told London-based BBC Persian TV station- a UK apparatus for spreading anti-Iran campaign- that Iranian officials must listen to Washington "if they want their people to eat".

In a related front earlier on the same day, Iranian President Hassan Rouhani referred to "the US lies" that the foodstuff, drugs and medical equipment were exempted from Washington's sanctions against Iran, and said, "This is incorrect. When the banking system is sanctioned, everything is affected."

The US Treasury Department announced all sanctions on Iran lifted under the 2015 nuclear deal would be back in force on November 5.

According to Treasury Secretary Steven Mnuchin, the sweeping sanctions will see 700 people blacklisted, including people who were granted relief under the 2015 deal, as well as over 300 new names.

Speaking to reporters on Friday, Mnuchin said the sanctions will also target payments made through the EU�s SPV channel.

He also warned global financial messaging service SWIFT that it could be punished if it doesn�t cut off financial services to entities and individuals doing business with Iran.

The Trump administration earlier agreed to allow eight countries to continue purchasing Iran�s crude oil after Washington�s sanctions on Tehran took place.
