Expect IR's retaliation against the U.S.

Given the IR's track record, the Islamic Republic will likely take retaliatory measures to even the score against the U.S. if it brands the IRGC as a terrorist group. Those measures could encompass intensifying proxy terrorist attacks in Iraq against U.S. forces or provoking another war with Israel via syria or Hizballah, or perhaps, more international hostage taking per usual since it has worked like a charm for the past 28 years. Here is IRGC's reaction to naming the guards as the foreign terrorist group:

Iran's Revolutionary Guards will grow in strength despite U.S. efforts to isolate the force, a Guards official said in remarks published on Thursday after Washington's threat to brand it a "terrorist" group.

Not only would the Revolutionary Guards not be isolated but rather it would actively continue its trend of growth with strength," the head of the political office of the Guards, named only as Javani, was quoted by the daily Jam-e Jam as saying.

"Americans have been fighting the Islamic system for 27 years and create plots against it. But the Revolutionary Guards have made defending the Islamic system its duty and will increase its capabilities in this regard day by day," he added.
