Iran issued another warning against the Trump Administration's plans to name the Iranian Revolutionary Guards (IRGC) as a terrorist organization, the New York Post reported.

The pledge came a week before President Donald Trump is expected to decertify the nuclear deal signed between Iran and world powers, including the U.S., in 2015.

“The Americans … are too small to be able to harm the Revolutionary Guards,” Ali Akbar Velayati, the top adviser to Iranian Supreme Leader Ayatollah Ali Khamenei, told Iranian news outlet ISNA Tuesday.

“We have all options on the table. Whatever they do, we will take reciprocal measures,” he added.

Velayeti's statements follow a similar threat issued Monday against the sanctioning of the Revolutionary Guards.

“We are hopeful that the United States does not make this strategic mistake,” Foreign Ministry spokesman Bahram Qasemi was quoted as saying on Monday, according to Reuters.

“If they do, Iran’s reaction would be firm, decisive and crushing and the United States should bear all its consequences,” he added.

Individuals and entities associated with the IRGC are already on the U.S. list of foreign terrorist organizations, but the organization as a whole is not.

Qasemi's warning itself came a day after IRGC commander Mohammad Ali Jafari warned that U.S. regional military bases would be at risk if further sanctions were passed on the IRGC.

“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 Islamic State all around the world,” he threatened.
