TEHRAN (FNA)- Iranian Supreme Leader's representative at the Islamic Revolution Guards Corps (IRGC) Ali Saeedi underlined that the country's influential role in the region and inefficiency of the military option against Iran made Washington to sit to the negotiating table with Tehran.

"One of the reasons for the US to opt for the path of negotiations with Iran was the inefficiency of the military option and they eventually came to the conclusion that the military option would not produce any impact on Iran's situation," Saeedi said in the Central city of Qom, addressing the Iranian people who had taken to the streets to mark the anniversary of the US embassy takeover in 1979 and commemorate the National Day of Campaign against Global Arrogance and the National Student Day in massive rallies on Wednesday.

"Another reason for the Americans to sit to the negotiating table was Iran's regional clout and power," he added.

Saeedi warned that the US ultimate objective is overthrowing the Islamic Republic, and described devising military plans, imposing sanctions and starting interaction with Tehran as different plots that have all been hatched by Washington to acheive this goal.

His remarks came after Supreme Leader of the Islamic Revolution Ayatollah Seyed Ali Khamenei cautioned that despite the nuclear deal and Washington's claims, the US is still seeking to change the ruling system in Iran.

"The reality is that the US objectives vis a vis the Islamic Republic of Iran have not changed at all and if they can, they will not hesitate a moment to annihilate the Islamic Republic but they cannot, and with God's help, they will fail in materializing this goal in the future too in light of industrious moves by the youth, increasing and deepening insight of the nation and Iran's progress," Ayatollah Khamenei said in Tehran on Tuesday, addressing the Iranian university students and pupils on the threshold of the 'Students Day' and the 'Day of Campaign against Arrogance' in Iran.

He referred to certain superficial and unreal flexibilities shown by the US during the recent nuclear talks with Iran, and said that the reality behind such behavior is that the US is still pursuing the same inimical policies towards Iran, which will never be forgotten by the Iranian nation.

Ayatollah Khamenei underscored that the US support for the criminal Zionist regime and the Saudi-led coalition's crimes against the Yemeni people reveals Washington's real face.

He referred to Iran's normal relations with other world states even those who show some hypocritical behavior towards the Iranian nation, but said the US which uses every pretext to hit a blow at the nation and annihilate the Islamic Republic is an exception to this rule, reiterating that "religion, wisdom, conscience and humanity all stand against such friendship".

Ayatollah Khamenei pointed to the US continued practical enmity towards the Islamic Republic, and said religious beliefs are the root cause of this enmity as it is the source inspiring the Iranian nation with resistance. "Therefore, they have targeted those beliefs using new instruments but our students and youth will foil such tricks and plots."
