It is extremely unlikely that the ISIS can be destroyed by only opposing it by air force only. It is unlikely that the ISIS will be contained by air force only. There is a stream of people, who want to join the ISIS, from all over the world. The ISIS, a Sunni Muslim group, has large support in Iraq. It’s governing a territory with the size like Great Britain, and administers about 8 million people, mainly Sunni Muslims.
In Iraq, ISIS means the answer of the Iraqi State support oppression from the Shi’ites. For the Muslim world, the Islamic State means the expansion of Islam and the successful Sunni Muslim battle against the Shi’ite Muslims, and the failing campaigns of the American led international coalition against ISIS.
The chaos of events in the Middle East does nothing to make people understand what actually is going on. Nobody makes even an attempt, and when they do, it’s quickly overshadowed by the noise of chaos an violence.
