US Secretary of State Mike Pompeo stressed Wednesday that President Donald Trump will increase pressure on Iran.
Tehran has also threatened to disrupt oil shipments through the Strait of Hormuz in the Gulf if the United States tries to strangle Iran's economy by halting its oil exports.
However, Pompeo refused to comment on whether sanctions waivers for countries that import Iranian oil would be extended past May, despite senators, like Ted Cruz of Texas, imploring him to end the waivers when the deadline comes up as they current generate billions of dollars for the Regime.
Responding to a question about the United States and its allies' efforts to isolate Iran in the region, he said, "Iran has a suitable situation for cooperation in the region".
Separately, Trump said on Monday he would name Iran's elite Islamic Revolutionary Guard Corps a terrorist organization, an unprecedented step that drew Iranian condemnation and raised concerns about retaliatory attacks on US forces.
Washington has already blacklisted dozens of groups and people for affiliations with the IRGC but had not previously targeted the organisation as a whole.
Sayyed Hassan Nasrallah, leader of the Shi'ite group, said that all options were on the table were Washington to take steps that "threaten our nation".
Baeidinejad said blacklisting the IRGC was only rhetorical and that he did not believe that Washington would ever instruct U.S. forces to really confront the IRGC and treat it as a terrorist force.
The members of Iranian parliament at Tuesday's session showed up in official uniforms of IRGC to announce their support and solidarity with the forces.
He said: "If you're the general counsel of an Asian bank or a European bank, your world changed when that designation came out yesterday". Iranian Supreme National Security Council, in retaliation, has recognized the US Central Command (CENCTOM) as a terrorist organization.
