Who: Ayman al-Zawahiri, co-founder and current leader of al-Qaeda.
Where: The Afghanistan/Pakistan border.
What he wants: To avenge the wrongs committed by Christians and Jews against Muslims over the ages, to have a single Islamic political leadership across the Arab world and to drive non-Muslims from Saudi Arabia, the home of Islam’s holiest sites.
What he does: Aside from championing murder of non-Muslims, he has recently been sending fighters to Syria and trying to convince ISIS to unite with all other jihadists against the supposed alliance between America, Russia, Europe, Shiites and Iran, and Bashar al-Assad’s Alawite regime.
How he can be stopped: Essentially assassination. He’s pretty elusive, though not when it comes to camera time (his most recent video was a jihadi sermon in August 2016). The US are going after him in the ‘global fight against terrorism’ in the same way they eventually got Bin Laden.
