Terrorists exploit hatred of Jews and Christians, hatred of Democracy, Free Speech, Freedom of Conscience, and Freedom of Association.
Come to think of it, so do One-Worlder Leftists.
Never mind.
ISIS is conducting a replay of the jihad of conquest in the middle east from the 7th century.
I believe that their aim is to reconquer the middle east and put it under their strict version of islamic law because they believe that the islamic rule instigated by Mohammed has become irreversibly corrupted. They are working on a rebuild.
After they have accomplished those aims, the goal becomes revisiting the conquest of eastern and western Europe which ultimately failed over many centuries.
They want to reaccomplish the original goals of their worthless prophet and do it the “right way” this time.
They are islam, they are dedicated, they need to be forcibly crushed into dust without regard to collateral damage.
