Former U.S. President Barack Obama attacked President Donald Trump and accused him of dragging the U.S. into 'a war with Iran that nobody asked for,' which he said led to a spike in the cost of living. In a campaign speech in Cleveland, Ohio, Obama defended the nuclear deal he signed with the Islamic Republic in 2015: 'Iran had no nuclear weapons because I got a deal and I didn't have to launch a single missile to do it. All it took was diplomacy.'
