This is a hilarious spoof video that pretends to show the (probably real) Iranian reaction to the nuclear deal that has been agreed to by the P5+1 powers, pointing out how ludicrous the deal actually is.
Although the translation in the video is false, the sentiment of the video and flaws it reveals are actually accurate. The nuclear deal with Iran is a terrible tragedy. Iran will receive between 500-700 billion dollars, which critics of the deal are certain will be used to fund even more terror around the world.
The nuclear deal also paves the way for Iran to acquire nuclear weapons within 10 years, even if they stick to the deal, which many feel is extremely unlikely. One has to wonder how much laughter there was behind closed doors in Iran, when the nuclear deal was actually signed.
