The US president made a harsh speech, replete with baseless accusations against Iran which was responded strongly by Iranian President.
Every 90 days the US president is supposed to give a report if Iran has adhered to the JCPOA; however, this time Donald Trump, a man who did not have any political background, announced that he would not certify Iran's adherence to the deal and used a very disrespectful, harsh rhetoric against Iran. He accused Iran of supporting terrorism and even referred to the Persian Gulf as “Arabian Gulf”.
