Iran pledged to respond with "firm and crushing" measures if the United States designate Iranian Revolutionary Guard Corps as a terrorist group.
Trump is to unveil his strategy on how he wants to contain Tehran in the region next week and is expected to decertify a landmark 2015 worldwide deal to curb Iran's nuclear programme, in a step that potentially could cause the accord to unravel. In the interview, Trump said he was "very unhappy" with the Iran nuclear deal and is considering a range of responses to Iran's bad behavior across the Middle East.
Trump is also expected to designate the IRGC as a terrorist organization as part of his policy on the Islamic Republic.
IRGC commander Mohammad Ali Jafari said that "if the news is correct about the stupidity of the American government in considering the Revolutionary Guards a terrorist group, then the Revolutionary Guards will consider the American army to be like the Islamic State in Iraq and Syria all around the world".

Iranian Foreign Minister Mohammad Javad Zarif said Iran purposefully excluded its military capability from the nuclear deal, as "it is not intended as leverage or a bargaining chip in future negotiations".
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.

"If reports on the USA decision to enlist Iran's IRGC as a terrorist group happen to be true, the Iranian force would also treat the American Army everywhere in the world and especially in the Middle East in the same way it deals with [ISIS] terrorists".
By the new law, Gen. Jafari was referring to the Countering America's Adversaries Through Sanctions Act (CAATSA) that Trump signed into law on August 2 after it passed a Senate vote.
"As we've announced in the past, if the USA new law for sanctions is enforced, this country will have to move their regional bases outside the 2,000 km range of Iran's missiles", the general stated.
"We have many options if Trump withdraws the JCPOA..."
Iran denies the allegations stressing that it's missile program is only for deterrent purposes.
A senior U.S. administration official, cited by the Financial Times, said on Friday that Trump would not seek the reimposition of broad sanctions that would risk collapsing the accord but was expected to announce new measures.
The deal, which was also supported by Britain, France, Germany, Russia and China, saw Iran agree to curbs on its nuclear programme in return for the lifting of global sanctions that had damaged its economy.
