Heshmatollah Falahatpisheh, who heads the parliamentary committee on national security and foreign policy, suggested a USA return to the nuclear deal would be needed before Tehran could think of negotiating.
If Iran senses "American steel they back down, if they perceive American mush they push forward - and right now they perceive steel", said Mark Dubowitz, chief executive of Foundation for Defense of Democracies, a Washington think tank that lobbied for a renegotiation of the Iran nuclear deal. "That's what America is trying to get Iran to stop doing".
Iranian President Hassan Rouhani said last week that Trump's repudiation of the deal was illegal and Iran would not yield to Washington's renewed campaign to strangle Iran's vital oil exports.
On Wednesday, U.S. officials told reporters the naval fleet of Iran's Islamic Revolutionary Guard Corps (IRGC) is planning to use 100 gunboats in the Persian Gulf to practice "swarm" tactics, an exercise that is usually reserved for the fall.
President Donald Trump has set out on a puzzling and ambitious policy towards Iran that looks increasingly focused on a summit that would deeply humiliate the Islamic Republic's leadership. "If they want to meet, I'll meet".
In response, Donald Trump sent an explosive, all-caps tweet telling Mr Rouhani to "never, ever threaten the United States again" and "be cautious!".
USA officials last week said Iran carried out a similar exercise, though Tehran did not immediately acknowledge it.
Mr Pompeo, in a speech to a largely Iranian-American audience in California, dismissed Mr Rouhani and Foreign Minister Javad Zarif, as "polished front men for the ayatollahs' global con artistry".
APIf Trump helped North Korea's image, imagine what he could do for Iran.
"North Korea already has a nuclear weapon and is more isolated form the worldwide economy, the worldwide stage, whereas Iran is pursuing a nuclear weapon and, I know it sounds extraordinary to say, but compared to North Korea is more integrated into the global economy", he said. European nations have been working to salvage the Iran deal by shielding investments in Iran with subsidies.
Coffey said he believes Trump's withdrawal from the Iran deal was an "opening gambit" for a new deal.
"Who knows exactly where this is going, what sort of meeting might take place or not take place", he said. The first batch of sanctions include, among others, sanctions on the acquisition of US dollar banknotes; sanctions on trade in gold and other precious metals; sanctions on direct or indirect sale, supply or transfer of aluminum, steel, coal and graphite to Iran; and sanctions on automotive sector.
