Islamic terrorists also harm Muslims in their own country, it's not just "fighting back" against America like some action revenge movie.
They live to disrupt. They launch violent campaigns in their own communities to enforce hardline sharia everywhere as far as they can reach. They brainwash boys into thinking that everyone outside of their narrow sect, is the enemy. They pay for the boys food, health and "education" over many years to put them on the jihad path, and I don't mean the good type of jihad.
Look up the Peshawar school massacre, and notice how that had nothing to do with America, it was terrorists being terrorists. Sneaking into a school and shooting as many kids as they possibly could. Yep... keep those media reports coming in, we won't stop reporting it.
