Throughout the column, Thomas Friedman expresses an informative, didactic, and judgmental tone when discussing terrorism and the Iran nuclear agreement. Friedman uses multiple facts, quotes, and dates, such as "billions and billions of dollars the Saudis have invested since the 1970s into wiping out the pluralism of Islam" and "9/11",to back up his claim.By appealing to logic, Friedman shows his informative, and also didactic, tone in the column. Through his logic, Friedman also incorporates appeals to emotion to create a solemn tone. His solemn tone asks the audience to look at their own views on the Middle East. Finally, Friedman also expresses a judgmental tone when he criticizes Lt. Gen. Thomas McInerney's view of the Iran nuclear deal. By giving his own opinion and reducing McInerney's opinion with logic, he shows his judgmental tone in the column.
