FNA- Top Military Aide to the Iranian Supreme Leader Major General Yahya Rahim Safavi said the US president is suffering from illusive thoughts and that's why he believes toppling the Islamic Republic is possible.

"The (attempts by) US presidents, including (Barack) Obama who was after change in Iran and Trump who seeks to overthrow the Islamic Republic, are all in illusion because the Iranian nation is a peace-seeking nation," Safavi said, addressing a forum in Tehran on Wednesday.

"Iran is not Iraq and Afghanistan because it has a wise leader, an elected government and prepared people and Armed Forces," he added.

Safavi said that the US and its allies' greed to force Iran to make concessions or wait for an overthrow of the Islamic Republic is an illusion and a strategic mistake which will bring defeat to Washington and the Zionist regime.

He underscored that Iran pursues the strategy of defense and effective deterrence and will certainly increase its security and defense power.

In relevant remarks on Sunday, Iranian President Hassan Rouhani blasted Washington's anti-Iran approach, and said that Trump had failed to isolate Iran in the world despite making huge efforts.

"We have been successful against the enemies in our foreign policy; we overcame the first big conspiracy. The US administration wanted to isolate Iran, but they got the opposite result,” President Rouhani said.

“The US administration thought that Iran would withdraw from the Joint Comprehensive Plan of Action (JCPOA) after they do, and resolutions and sanctions would come back,” the Iranian president added.

President Rouhani underlined that in the first phase, "we did not let the US achieve its goals and their conspiracy failed".

"Apart from a few countries and a fake regime, the entire world stood up to the us and this means that Iran’s foreign policy has been successful, while once all countries were a part of sanctions against Iran and the UNSC would vote against Iran," he added.

Trump announced on May 8 that the US would no longer remain part of the JCPOA and promised to re-impose the highest level of economic sanctions against Iran in response to Tehran's development of its nuclear program.

After Trump's declaration, the Iranian government issued a statement, calling the US withdrawal as "unlawful". The statement underlined Iran's prerequisites for continuing the deal with the five world powers after the US pullout of the agreement.

"Iran, as a country that has remained committed to its legal obligations, will pursue the US Government’s decision to withdraw from the JCPOA as provided by the mechanisms and provisions of the accord, and if the US withdrawal is not fully compensated and the full interests of the Iranian people are not met and guaranteed – as stated in the accord and as outlined by Iran’s Leader on 9 May – it will exercise its legal right to take whatever reciprocal measures it deems expedient. Other parties to the JCPOA, and especially its three European signatories, must take necessary action to safeguard the accord and to implement their commitments – which they proved incapable of fully performing even while the US was nominally a party to the deal, due to the obstructions by the Trump Administration – and to proceed from giving pledges to taking practical action without any preconditions," it said.

"None of the provisions or timeframes within the JCPOA, which were the subject of twelve years of negotiations, are negotiable in any manner. The US, which has through its meddling and erroneous policies ignited extremism, terrorism, destruction, war and child killing in our region, is in no position to issue any diktat about the Islamic Republic of Iran’s lawful presence within its own region nor its effective support for the peoples of Syria and Iraq in their endeavor to fight extremists. The US and its allies, which through their support for the regime of Saddam Hussein, including equipping it with chemical weapons and the most advanced military equipment while blocking Iran’s access to any means of defense victimized the Iranian people for eight years, and currently turning our region into a powder keg through their sale of hundreds of billions of dollars of useless advanced weaponry devouring the financial resources of the region, are in no position to impose restrictions on the Islamic Republic of Iran’s lawful means of defense, including defensive ballistic missiles which have been designed to carry conventional weapons based on the bitter experiences of the war with the regime of Saddam Hussein. Indeed, such efforts explicitly violate the principles of international law, and the Islamic Republic of Iran’s legitimate right to self-defense under Article 51 of the United Nations Charter," it added.

"As announced by the President of the Islamic Republic of Iran on 8 May, the Foreign Minister has been tasked with the duty of taking the necessary measures to obtain required guarantees from the remaining parties to the JCPOA as well as Iran’s other economic partners, and to immediately report the results of this mission. Meanwhile, the President of the Atomic Energy Organization of Iran has been tasked with taking all necessary steps in preparation for Iran to pursue industrial-scale enrichment without any restrictions, using the results of the latest research and development of Iran’s brave nuclear scientists."

"The people of Iran will with calm and confidence continue their path towards progress and development and the Government of the Islamic Republic of Iran has foreseen all necessary measures to facilitate this under any circumstances," the statement continued.

"The Islamic Republic of Iran, as a secure and powerful state, which derives its security and economic development from within, relying on the prudent participation and resilience of its brave and civilized people, seeks constructive and dignified engagement with the world, and as shown by its implementation of the JCPOA despite the United States’ continuous violations, is a trustworthy and committed partner for all who are prepared to cooperate on the basis of shared interests and mutual respect," it reiterated.
