The chief commander of the Islamic Revolution Guards Corps (IRGC) says Iran will treat US troops like Daesh terrorists who will have to move their military bases farther from Iran's borders if Washington blacklists his force.

Major General Mohammad Ali Jafari's warning on Sunday came after reports that US President Donald Trump is expected to announce new measures against Iran, including the prospect of additional targeted sanctions and the designation of the IRGC as a terrorist organization.

"As we have announced in the past, if America's new law for sanctions is enforced, this country will have to move its regional bases outside the 2,000 km radius of the Iranian missiles' range," the ISNA news agency quoted him as saying.

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.

Jafari said Iran “deems the implementation of CAATSA equal to America’s unilateral withdrawal from the JCPOA,” which will allow the country to exponentially enhance its missile capabilities.

The JCPOA stands for the Joint Comprehensive Plan of Action - the nuclear accord which Tehran reached with the US and other countries in 2015 to limit its nuclear program in exchange for lifting of sanctions.

Trump is expected to announce soon that he will "decertify” the deal in a step that potentially could cause the accord to unravel.

"We will use the opportunity of the stupid behavior of the Trump government to achieve a leap in defense, missile and regional programs," Gen. Jafari said.

A senior US 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.

Those measures will include additional targeted sanctions, the blacklisting of the IRGC and the adoption of a tougher stance on what Washington calls Iranian proxies in Syria, Iraq and Yemen, the official was quoted as saying.

Jafari said, "If the scattered news about the stupidity of the US government regarding the IRGC as a terrorist group is correct, the Guards will also consider the American military all over the world, especially the Middle East, as equal to Daesh."

Senior US officials have been cited as saying that the Trump administration intended to employ a strategy that would “address the totality of Iran’s malign behavior” in the region, meaning Iran's support for the Syrian and Iraqi governments and resistance groups opposed to the US and its allies pushing for influence in the Middle East.

Jafari said, "If the ultimate goal of the Americans in raising such issues is to negotiate with Iran about the region, they have chosen a completely wrong path."

New US sanctions, he said, will eliminate the chance of any engagement forever.

"These sanctions will cap the JCPOA experience for us, and the experience is that dialog for America is a tool for pressure and hostility rather than interaction or problem-solving," Jafari added.
