The warning came after the White House said on Friday that President Donald Trump would announce new USA responses to Iran's missile tests, support for "terrorism" and cyber operations as part of his new Iran strategy.
Spokesman Bahram Qasemi said "I hope that the US ruling body would not make the strategic mistake, but if it does so, then Iran's response will be firm, decisive and crushing and the USA should accept its consequences".
The statements by U.S. President Donald Trump that the deal is an "embarrassment" and that Iran is not fulfilling the "spirit" of the deal, were contradicted by the United Nations official.
Trump is also expected to designate the IRGC as a terrorist organization as part of his policy on the Islamic Republic.
"As we've announced in the past, if America's new law for sanctions is passed, this country will have to move their regional bases outside the 2,000 km range of Iran's missiles", Guards' commander Mohammad Ali Jafari said, according to state media.
This article has been adapted from its original source. Federica Mogherini, the European Union's diplomatic chief, has stated that Iran's compliance with the terms of the deal has been verified several times.
"Sunset clauses", Iran's ballistic missile development and testing, and an inspections regime lacking the bite to gain necessary access into the regime's controversial military sites.
What drove Trump to this decision probably never will be known.
The Iran deal has been hailed by its supporters as a landmark agreement that serves to advance nuclear nonproliferation.
Iran has said, many times and in high dudgeon, that there can not be any renegotiation of the deal and that any re-imposition of sanctions will cause it to immediately cancel the deal.
Reuters reported that Trump "wants to look for a broad strategy that addresses all of those problems, not just one-offing those", she said. To date, despite the administration's repeated criticism of Iran, Trump and his Cabinet have made virtually no progress in convincing Germany, France and other key US allies to join the U.S.in demanding that Iran agree to change the JCPOA's terms.
By the time of his 2017 re-election, Rouhani increasingly criticized hard-liners within Iran who criticized him and the atomic deal for giving too much away to the West, especially the US, still the "Great Satan" for some even decades after the 1979 Islamic Revolution.
Administration officials have been signaling publicly and privately that they will ask Congress to pass new legislation on Iran following Trump's announcement.
Trump has threatened to withdraw his endorsement of the nuclear deal with Iran next week, leaving its survival in the hands of a divided Congress. This is where critics say the deal falls short, because by allowing for some enrichment, Iran's nuclear program is effectively being legally codified.
The President's refusal to certify the deal will open a 60-day window for Congress to reimpose sanctions on Iran. The U.S has been pushing Iran not to accept the JCPOA and to have Iran violate the deal. "He is also largely responsible for the horrendous Iran Deal!" In theory, the deal prevents Iran from being able to rapidly assemble a nuclear weapon in the near future.
Former CIA Director Leon Panetta has called United States President Donald Trump's comment "calm before the storm" a "play for attention".
The most likely effect is that sanctions will not be re-imposed and decertification will be a warning to Iran.
Donald Trump's least presidential moments so far..
Macron and our other North Atlantic Treaty Organisation "partners" are loosing their foreign ministers and other lobbyists on Capitol Hill this week to persuade Congress that Trump is wrong and that they shouldn't impose new sanctions no matter what Trump wants.
