ISIS tries to lure US into airstrikes against civilians
ISIS is doing this to pander to the anti-war left in the West, such as the professor who was sickened to see someone give up their first class ticket to a soldier. They are playing to the useful idiots on the left and the American's innate humanity. The Iraqis have also alleged that ISIS is booby trapping these buildings to blow up the civilians and then blame the deaths on US airstrikes. Most of their tactics such as this one are war crimes that the blame America first left is mostly silent about.
Islamic State fighters forced residents into buildings, then tried to draw an attack in the hope that a rising civilian deaths would lead to fewer airstrikes, an American spokesman said.
