ISIS has just made an Strategic Mistake of epic proportions. If there is one place in the world that is considered to be the cultural centre of the world, it is Paris. Every civilized country in the world has an embassy or consulate there. Paris is probably the closest place on Earth to neutral ground. By attacking Paris they have demonstrated to everyone that they are Hostis Humanis Generis.

Latin: Hostis Humanis Generis.
Translation: Hostile to Humanity in General.
Transliteration: Enemy of all Mankind.
