Is for them never to have been there in the first place. In the expanding annals of blog futility, we've tried to keep track of the more bogus news stories about ISIS: the US$500 million bank robbery, the tweet to Lionel Messi, the Rolex watch on the Caliph, and the alleged order of FGM for women. At first there was enough supporting evidence backing up a claim of a crisis of Mount Sinjar that the 50,000 fleeing people number seems to have slipped through the filters and motivated an American intervention which strongly benefitted the Kurds. Now, the Pentagon says there's nothing like that number of Yazidis still there, and it's not entirely clear where they went.
Remember, not everything you read about ISIS is true.
