Just a quick example of some bias. Israel warned Syria that if they were to be attacked they would hit back. Pretty common thing in the Middle East. So the Huffington Post decided to spice it up with a biased picture:
In media relations this is known as the "crazy position" because it makes the person look crazy. The Huffington Post could have chosen any other picture from the many that it has, but they decided just by sheer coincidence to choose the one of Netanyahu looking aggressive paired with a 'warmongering' headline. Any pictures of Assad in the "crazy position" have yet to be found.
