It turned out it wasn't that many either, most were already living on the mountain the humantarian situation was normal. The pentagon confirmed this which is why they halted any operations there. The important thing for them is to secure some areas, it wasn't about Yazidi's. Almost all people in Iraq are victims to this conflict as well. But, US media needs to secure public support for operations overseas so this story convinced the public.
Of course the guy says the same thing in every thread, he keeps whining that people are condemning Israel on social media. Because they are waking up to the truth. On global media they keep defending Israel as always, but social media and the general public are appalled by their actions.
