Trump aggravating and irking Iran on a wider context is of no surprise. Every US president for the last 50 years who is aiming to be re-elected has had to coincidentally deal with either a terrorism threat or an evil enemy abroad (1983 Reagan and Nicaragua, 1996 Clinton and Khomar Towers, 2003 Dubya and catastrophe in Iraq following 9/11, 2011 Obama finally finding Osama). This is merely just part of the manual for re-election and presidency.
