The Majlis speaker said the Republican senators have clarified the meaning of "mistrust" toward the United States through sending a letter to Iran on a prospective nuclear deal.
"The letter shows that the Israeli regime's support (for the US lawmakers) has created a political frivolity disorder," Ali Larijani said in an address to the Majlis on Sunday, adding, "The senators themselves have clearly defined the meaning of mistrust toward the United States to the public."
"It reveals the true nature of the US ruling system that wrongly claims to be in charge of managing the (world's affairs)," IRNA quoted him as saying.
The open letter, signed by 47 Republican senators and released last week, said any nuclear deal with Tehran could only last as long as US President Barack Obama remains in office.
Pointing to the remarks by Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei on Thursday, he said, the Leader rightly referred to the letter as an indication of "the collapse of political morality" in the United States.
In an address to members of the Assembly of Experts in Tehran, Ayatollah Khamenei said, "The American senators announce officially that after the current US administration, they will consider the agreement invalid. Isn't this the ultimate sign of the collapse of political morality and internal disintegration of the US system?"
The senior lawmaker expressed support for the nuclear negotiating team, noting that in response to the senators' move, the negotiators should not merely "announce their political stance" and the letter must have alarmed them not to let the other side impose its "reactionary" views on the negotiations.
He also called on the diplomats to exercise more "vigilance" to "foil" such plots.
Ignorance of Commitments
In another development, the head of Iran's Strategic Council on Foreign Relations underlined the Leader's remarks, saying the US lawmakers' move shows their "ignorance of their national commitments", IRNA reported.
In any country, when a popular government adopts a decision, all officials and institutions and next administrations are expected to abide by the decision because one of the basic principles of international law is that "a change in the domestic policy or even a change of government should not interfere with the country's international commitments," Kamal Kharazi stated.
Decisions in the United States are made under the powerful influence of the Israeli regime rather than based on national interests, the former foreign minister said, adding that the senators have withheld their support for their government to back Israel's extremist position.
"Today, no one can deny the reality and power of the Islamic Republic of Iran and the current US administration has acknowledged it and is ready to recognize Iran's capabilities as an influential regional power."
"Accordingly, the acknowledgment has been made not as a gesture of goodwill but out of force," he noted.
