AVA- "If the Americans make such a silly move and endanger our national security, we will implement and put reciprocal measures on our agenda based on the policies of Iran's Islamic establishment," Major General Mohammad Ali Jafari said on Sunday.
He added that if the US designated the IRGC as a terrorist organization, the American army and security forces would not experience peace and calm in the Middle East anymore.
The administration of US President Donald Trump is expected to designate the IRGC as a foreign terrorist organization as early as next week, according to a US official.
The designation decision, formally under the State Department's purview, has been made as part of the White House's increasingly aggressive strategy towards Iran.
The US has already blacklisted dozens of entities and individuals affiliated with the IRGC, but not the entire force.
The IRGC, which has roughly 125,000 military personnel and enjoys growing public support, is also actively cooperating in construction, infrastructure and relief projects.
