In what sense is this wrong? Everyone from all sides is saying this: that ISIS is different from other radical Muslims in their effective use of propaganda. Have you seen some of their videos? They are crazy, and I&#x27;m not talking about the beheadings. They use &quot;Western&quot; techniques, including stuff like slow-motion for dramatic effect.<p>Public beheadings, whether televised or not, are <i>always</i> propaganda, a show of force, a message to the common people. Public punishment is sometimes a barbaric form of entertainment, which is a form of propaganda as well. Historically this was the case in most countries, including those in Europe.<p>In the case of ISIS, I also think they are meant to shock Europe and the US into action. A war between Islam and the West is just what ISIS needs.<p>I find your explanation about Mohammed utterly unconvincing, because most Muslims don&#x27;t go around beheading people, only <i>some</i>. ISIS and people from backwards, poverty-stricken countries&#x2F;communities do, but that&#x27;s a different issue.
