Yes, they sure could. If more of this happened, maybe beheadings of citizens from other countries would stop. Better yet, put together a coalition of countries like Israel and Jordan and let them bomb ISIS into extinction.

Sorry, but Israel does not benefit from destroying ISIS. Muslime inner-fighting is not a bad thing, especially when you are Israel and are hated by Muslimes of all types. The more they are busy killing themselves, the less time and resources they have in killing Jews.
