ISIS’ own alleged agenda of transforming the world into a “caliphate” is cartoonishly absurd. In reality, it is clear that ISIS shows up and exercises force in regions of the world the US and its allies cannot intervene in directly. This includes North Africa, the Middle East, and even as far as Asia.
Far from a “conspiracy theory,” it would be the US’ own Defense Intelligence Agency (DIA) that would admit as much in a leaked 2012 report (.pdf) which stated:
If the situation unravels there is the possibility of establishing a declared or undeclared Salafist principality in eastern Syria (Hasaka and Der Zor), and this is exactly what the supporting powers to the opposition want, in order to isolate the Syrian regime, which is considered the strategic depth of the Shia expansion (Iraq and Iran).
To clarify just who these “supporting powers” were that sought the creation of a “Salafist” (Islamic) principality” (State), the DIA report explains:
The West, Gulf countries, and Turkey support the opposition; while Russia, China, and Iran support the regime.
