IS, the Taliban,Al Qaeda,Boko Haram,Al Shabaab,Hamas,Hezbollah,etc etc all have one common denominator, an Islamic Global Caliphate objective.
Islamic expansion through terrorism is nothing new, it is after all, its raison d’être.
To establish a Global Caliphate is the objective of Islam, achieved since Islam's inception by violent subjugation,the sexual slavery of women and children,extortion,and murder.
Nothing has changed, because Islam has not changed.
This is how any Muslim must live, if he wants to be true to his faith, otherwise he is ranked as an hypocrite.
The three video presentations reveal the truth.
