This picture is about the "internal displacement in Iraq". International Organization for Migration recorded that because of the terrible conditions during the Iraq wars, there were "nearly 3.2 million displaced", and most are "living in critical shelter arrangements" (IOM Iraq Chief). The wars are causing civilians to lose their homes and families, and facing shortages of food and basic resources.
Because of US intervention in its affairs, ISIS is trying to exact revenge on the US. Al Bayan radio said, "We say to the defenders of the cross, the U.S., that future attacks are going to be harsher and worse…The Islamic State soldiers will inflict harm on you with the grace of Allah. The future is just around [the] corner."
ISIS has proven to be a tech-savvy adversary and astutely uses the Internet to achieve its schemes.
