What's disgusting is that our "wonderful" American government is completely behind the creation and ongoing sustenance of ISIS.
Yes, they do evil things. Yes, they are wicked. But don't ever forget whose side they are on, and who they are working for. They are doing a job -- create terror and horror, to push their master's agenda. They are a creation, a servant, and a tool of the US Government.
For those aware of the true nature of the world, who controls things, etc. the whole thing is ridiculous. The United States claims to be fighting ISIS, while they actually SAVE ISIS, give them weapons, air rescue, etc. while bombing hospitals, electric grid, oil refineries, infrastructure, etc. to weaken and degrade Syria, so we can get rid of their President Assad. The US basically gives ISIS valuable air cover/support so they can conquer and hold territory.
