@politically-wrong,
Jihad is just their word for crusade, which the US media is avoiding like the plague. Perhaps that's because compared to atrocities like the Inquisition, cutting off a few heads doesn't seem so radical. At least they aren't trying to torture the devil out of them first.
The propaganda machine also doesn't want Americans to know the source of radical Islam was the Ottoman Empire, the remnants of which is modern day Turkey, a US ally. So I'm afraid the outrage seems somewhat two-faced to me, as our government is clearly playing both sides of the fence.
