His remarks came few hours after IRGC top Commander Major General Mohammad Ali Jafari said imposition of new sanctions by Washington against Iran means a U.S. withdrawal from the nuclear deal, and warned that the U.S. should leave the region and stay 2,000km away from Iran if the Countering America's Adversaries Through Sanctions Act (CAATSA) comes into effect.
IRGC Commander Major General Mohammad Ali Jafari also told a gathering of military commanders in Tehran on Sunday that the sanctions would fail to achieve their goal of dragging Iran to the table of negotiations aimed at curbing its regional clout, IRNA reported.
Iran is warning the United States against designating its Revolutionary Guards Corp as a terrorist group and says U.S. regional military bases will be at risk if new sanctions are passed.
Jaafari cautioned the United States government of the dire consequences of imposing new sanction against Iran.
The new Iran policy also follows reports that Trump will soon announce a decision to "de-certify" the landmark deal on Iran's nuclear program, opening the door for the re-implementation of crippling economic sanctions.
Trump has until October 15 to recertify the deal.
He warned that the Islamic Republic would move to step up its defensive military power in response to Trump's hostile stance on the action plan.
"If the US is stupid enough to designate the IRGC a terrorist group, then the IRGC will treat the US Army the way we treat ISIS", he stated.
"The Americans should know that the Islamic Republic of Iran will use the opportunity provided by the Trump administration's stupid behavior towards the nuclear deal to make a leap in its conventional defense, missile and regional programs", he added.
Jafari's remarks came two days after US President Donald Trump claimed Iran "supports terrorism and exports violence, bloodshed, and chaos across the Middle East" and suggested it has "not lived up to the spirit of" the nuclear deal.
Notably, the U.S. Treasury Department has already designated the IRGC Qods Force, a wing of the IRGC, a terrorist entity back in 2007, but stopped short of declaring the entire IRGC a terrorist entity.
Iran's ballistic missile program has triggered the discontent and concerns of other states, in particular, the United States.
