The US sanctions may be tanking the Iranian economy, but by the looks of this video, their resolve to fight back has not been broken. It is believed that Iran is responsible for striking four oil tankers. Two of the tankers belonged to Saudi Arabia and at least one of them was destined to Saudi port to deliver oil back to the US. While the investigations are on going and Iran denies any responsibility for the attacks, there was this eery billboard proudly displayed for all to see in Vali-e Asr Square in Tehran. Take a look at the video.
