ISIS was a tool who was suppossed to use "religion" to do its creators bidding! Alas, it got a taste of power! Now it has its own agenda, that does NOT coincide with doing its "master's" bidding!
ISIS/ ISIL/
a foreign policy tool to overthrow President Assad of Syria. Started out splitting from Al Qaeda. Al Qaeda deemed ISIS too extreme!
After Bush destroyed Iraq, Al Qaeda entered to destabilize the country! Saddam Hussein kept Al Qaeda out.
Bush got rid of Hussein' Ba'ath party. This meant lots of people lost their lively hoods, who had joined the party just to get a job, like police, soldiers etc.
some of them joined ISIS.
The ISIS ideology is very close to S Arabia's.
ISIS is predominantly Sunni, its enemies everyone! It wants to rule like a 7 the century caliphate. For ISIS religion is a fig leaf! Just a tool to gain power.
Only when ISIS started to threaten US' oil interests in Iraq was it "deemed" an enemy. When ISIS entered Syria to overthrow Assad it was left well alone!
4 years on from when civil war ignited in Syria, antagonism against ISIS means Assad is still in power, there is a stalemate, because Syria' secular society is petrified if intolerant religious "nutters" gain power. Syria: 4 million have fled, over 6 million are displaced inside Syria, 500,000 have died.
US and its "allies" can NOT find any moderate opposition!
Originally dividing up Syria was seen a "prize", amongst those who backed funded, trained, and armed ISIS. ISIS' leader learnt his art in an US prison. ISIS was just a tool, but the endless bombing, and drones in the middle east gained it followers, thanks to its self promotion on social media, amongst European countries.
If US and a coalition of 60+ countries can't defeat it, it implies something. Iran (is Shia) / Russia/ and Syria are also required to defeat ISIS, but they are not welcomed.
