How have leaders of terrorist groups abused Jihad?

Leaders of terrorist groups such as Osama Bin Laden have abused Jihad by using its past interpretations to justify their agenda. In the medieval era, the Sunni Islamic Scholar Ibn Taymiyya declared the military inferior Mongols, who Mamluks had surrounded with arrows at an instant - having Jihad forced on them by mamluks was not just permissible, but obligatory; a tyrant attitude of leaders who abused to use Jihad for their advantage rather than Allah’s.
