The threat of ISIS grew rapidly this year, particularly for people in Iraq. There's also real fear among Americans too, who had staggering levels of awareness of ISIS' murder of American journalists — 94 percent in the most recent poll (compared to 79 percent who had heard about Syria's use of chemical weapons).
But nothing illustrates the story as clearly as the president's own comments this year on the terrorist group. Watch above how President Obama went from a joke about ISIS in January to outlining our developing war against them.
