ISIS serving Israel
The biggest service provided by ISIS to Israel is the destruction of the two important Arab countries, Syria and Iraq, hoping that such destruction will hit other countries like Egypt and Saudi Arabia as well. Libya and Yemen are also on the list with the Gulf countries.
However, it is really strange that many opinion polls proved that ISIS is supported by the majority of the Muslims in the Arab countries. This gives ISIS much power and support, especially after Al-Azhar refused to call ISIS infidel. This should have something to do with the ultra fanatic curricula of Al-Azhar and its institutions and universities.
