This is the best in depth look at the Islamic world I've seen anywhere. It is very long and thorough and deals with the variety of factions and their leaders who actually compete within Islam for supremacy. Most of the leaders don't like each other and each one's followers passionately disagree with others and are loyal to theirs.
The IS devotion to early violent Islam is drawn from the Koran. To say they are not Islamic is incorrect. Dismissing IS like that is a mistake.
This article is worth the time to read.

"Properly contained, the Islamic State is likely to be its own undoing. No country is its ally, and its ideology ensures that this will remain the case. The land it controls, while expansive, is mostly uninhabited and poor. As it stagnates or slowly shrinks, its claim that it is the engine of God’s will and the agent of apocalypse will weaken, and fewer believers will arrive. And as more reports of misery within it leak out, radical Islamist movements elsewhere will be discredited: No one has tried harder to implement strict Sharia by violence. This is what it looks like."



Here's an excerpt on how Obama is likely being viewed by the Islamic world.

"Western officials would probably do best to refrain from weighing in on matters of Islamic theological debate altogether. Barack Obama himself drifted into takfiri waters when he claimed that the Islamic State was “not Islamic”—the irony being that he, as the non-Muslim son of a Muslim, may himself be classified as an apostate, and yet is now practicing takfir against Muslims. Non-Muslims’ practicing takfir elicits chuckles from jihadists (“Like a pig covered in feces giving hygiene advice to others,” one tweeted).

I suspect that most Muslims appreciated Obama’s sentiment: the president was standing with them against both Baghdadi and non-Muslim chauvinists trying to implicate them in crimes. But most Muslims aren’t susceptible to joining jihad. The ones who are susceptible will only have had their suspicions confirmed: the United States lies about religion to serve its purposes."
