This type of bluster is very Arabic in nature.
They are all talk and bluster. You shoot a couple of them and they run away. My father in law, who spent some time in WWII in Northern Africa would say this all the time. And it is played out over and over again.
American culture is that we mean what we say. That is not true in the rest of the world. Bluster, boasting, and lying are the norm.

Tell that to the Russians and Americans who fought and are still fighting in Afghanistan.
